I'm a little concerned potential maintenance fees. Transportation costs should be a little higher. Resorts with many busses, like SSR and OKW, have higher transportation costs. Fort Wilderneas has many busses, both internl and external, plus boats.
I'm guessing that insurance costs may be higher than than that of a multifloor building with multiple units sharing one roof (lower floors have much lower risks). Fort Wilderness obviously had many trees that can fall and cause damage.
I'd guess estimates to repair and replace will be higher. Can't expect maintenance to be less than other resorts, and there are added elements with steps, buildings exposed to elements, etc. Every other DVC resort is expected to have its building last through length of contract. The cabins are glorified mobile homes with shorter lives and, if like the retiring cabins, will need to be entirely replaced in 25 years. Presumably these costs, at least for first replacement, are own owners. (Related, curious if ownership will be to part of Cabin #X or like a sublease to ground Cabin Site #X).
Housekeeping had more costs with need for carts. I don't know if it takes any longer considering distances between cabins and rain. On distances, they can assume if a cart or car is parked that room is still occupied, but same assumptions can't be made on other days. I know it's small to consider, but the difference between walking to three straight rooms in a hall and three straight cabins (driving to, walking up to, turned away, walking to cart, driving to next cabin, walking/turned away/walking back, etc adds up. On rain it's not like they're inside a corridor moving between units. It wouldn't surprise if more housekeeping is needed to turn rooms over timely to get around rain, travel times, etc.
Even member activities, there's more to do at FW than other resorts.
Even utilities can be a smidge higher. Even waste collection costs more.
Up and down the maintenance fee list I don't see much there will "for sure" be lower than average. But there are many things that costing a few more cents here and there that add up. But maybe it's offset if ad valorem taxes come in lower.
Not anything to lose sleep about but just something to keep in mind when announcements are made, so we're not surprised if we end up surprised (which sounds like a Yogi Berra phrase).
