There's a ton of things to do at the Fort, so make a couple days for Fort Exploration. I think in one of the stickies has an activities sheet for the month... pool games, movies, any special happenings.
Halloween is an amazing time to visit the Fort. And Halloween weekend books up FAST.
Like the PP said. pick your dates, and then check the reservation system with dates for 2 weeks. If that's available, knock off a couple days, until you get to the days you actually want, and the kind of site you want. There's no penalty for booking 2 weeks, then calling and knocking off days, as long as you do it within policy.
There's two ways of booking... You can do a package room and tickets together, and this will allow you the option of the Dining plan (good idea if you want to do a lot of character meals as that will pay for itself). This has to be paid off 45 days prior to your trip.
Or book room-only. The policy is a bit better on this. You can cancel up to 7 days prior to arrival with no penalty, and you can make changes up to check in. Now if you cancel in the last 6 days, You will pay for one night. But only one night's deposit is due, the rest can be paid upon check in.
there were times when I booked a night too soon, called and said hey, I'm not making it tonight, they'd take the one night off. And I didn't have to pay a thing. I've also checked in and asked to take days off at the end. Never had a problem with it.
The Fort is great. If you've got the time... take the whole two weeks. There's people that camp there for a month or two at a time. I've met families with home school kids staying there for a month. Now that's awesome schooling.
If you are a
AAA member, just tell the CM and they will see if any discounts can be applied. Just remember, certain promos aren't eligible at the fort. Like in august when they do free dining, doesn't work for those staying at the fort campground.
I'd suggest calling. Because they can generally answer any questions you might have. And make the selection process easier. And sometimes they can make reservations appear that don't want to online. And there's no price difference for booking online or calling.
