Every small park gets the call eventually. A traveling nurse on a 13-week contract. A remote worker who wants to spend a season somewhere green. A couple between a house sale and a closing date. They don't want a weekend — they want a site for a month, maybe three.
Guaranteed money sounds wonderful, especially in April. The question is whether it's still wonderful in July. Monthly guests can be the steadiest revenue a small campground has, or a quiet way to sell your best inventory at half price. The difference is math you can do on one sheet of paper.
Price against the month, not the nightly rate
The common mistake is anchoring on your nightly rate. Say a full-hookup site lists at $45 a night and a guest asks for a monthly rate. Quote $600 — a typical small-park number — and you've just sold that site for $20 a night. Whether that's smart depends entirely on what the site would have earned otherwise.
Run the comparison against that specific site in that specific month. A back-row site in May that would realistically sell twelve transient nights at $45 earns about $540 — the monthly guest beats it, with zero turnover, zero cleaning, and one payment instead of twelve. The same site in July at near-full occupancy would earn roughly $1,200 — now the monthly guest costs you half.
So a monthly rate isn't one number. It's a bet on occupancy, and the bet changes by season. This is the same discipline as seasonal pricing for your nightly rates, applied to a 30-night block: price the month against what the calendar would actually have produced, not against the rack rate.
Electric is where the margin goes to die
A weekender runs the air conditioner for two days. A monthly guest lives there — a space heater through the shoulder season, A/C around the clock in August, an electric fireplace in the rig because propane costs money and your pedestal doesn't. If electric is baked into the rate, the guest has no reason to conserve and you have no way to notice until the utility bill arrives.
The clean answer is a metered pedestal, billed monthly at your utility's rate. If your sites aren't metered, charge a separate flat electric fee, say so plainly in the agreement, and revisit the number by season. This isn't nickel-and-diming; it's the difference between a monthly rate that holds up and one that quietly loses money every August. The parks that get burned are usually the ones that set a monthly rate in October and discovered what it meant in August.
The tax line changes around day 28
In many states, a stay past a certain length — often 28 or 30 days, sometimes longer — stops counting as short-term lodging for tax purposes, and the lodging or occupancy tax falls away. That's good news for the guest's bill, but it changes your bookkeeping: what you collect, what you remit, and what your records need to show if anyone ever asks.
The thresholds and rules vary by state, so don't guess. Know your state's line before you quote the monthly rate, so the quote and the tax treatment match from day one.

The trade-off nobody puts in the brochure: tenants
Here's the honest downside. In some states, a guest who stays long enough can start to accrue tenant protections. If that happens and things go bad — nonpayment, a rig that stops moving, a situation you want ended — you may not be asking a camper to leave anymore. You may be in a formal eviction process, with notice periods and court dates.
Most owners meet this problem exactly once, because once is enough. The protections are simple and boring:
- A written agreement with a defined end date, where renewal is a decision, not a default.
- Terms that make clear this is a campsite license, not a lease — and stay lengths that respect whatever line your state draws.
- A conversation with someone who knows your state's landlord-tenant law before your first 90-day guest, not after.
None of this is a reason to say no to monthly guests. It's a reason to say yes in writing.
Cap the count, and pick the sites on purpose
Monthly guests change the character of a park. Transient guests are on vacation; monthly guests are living their lives. Both are fine — mixed carelessly, they create friction. A few practical habits help:
- Group the monthly sites, usually in a back row, and keep your premium pull-throughs for transient traffic.
- Cap the number. Booking windows keep getting shorter, and last-minute demand can't book a site that's occupied until Labor Day. Decide how much of your park you're willing to commit, and hold the line in busy season.
- Consider a split calendar. Plenty of parks run monthly stays October through May and go transient-only for the peak months. If your demand is brutally seasonal, that's the best of both.
The say-yes checklist
When the math works, make the yes clean:
- Written agreement with a defined end date.
- First month plus a deposit collected up front, before arrival.
- A card on file, charged automatically each month — chasing rent is a job you didn't apply for.
- Electric metered, or a stated electric fee.
- A ten-minute phone call before you commit. It tells you most of what you need to know.
Where software fits
Long stays are where paper grids and spreadsheets quietly fall apart. A 90-day block crosses rate seasons, collides with holiday-weekend pricing, and needs a charge run by hand every month — which means it gets forgotten every month at least once. If you're evaluating booking systems, ask specifically how they handle stays measured in months, not nights; many treat them as an afterthought.
Bunkpost handles long-term stays directly: the calendar blocks the full stay across seasons, the card on file gets charged on schedule, and the records sit next to your nightly bookings instead of in a side binder. And because Bunkpost is free for the park and funded by a flat $3 fee the guest pays once at booking — never a percentage — a three-month stay costs your guest the same $3 a weekend does. On a percentage-fee platform, a long stay is exactly when the fee gets ugly.
The takeaway
A monthly guest isn't a policy question — "do we take them?" — it's a pricing question you answer per site, per season. Compare the monthly rate to what the site would really have earned, meter the electric, learn your state's tax and tenancy lines, put the yes in writing, and cap how much of the park you commit. Do that, and monthly guests become what they should be: the quiet floor under your revenue in the months that need one.
If you're running long-term stays off a paper grid today, how Bunkpost works is a two-minute read — and since it's free for your park, trying it costs nothing but an afternoon.
