Though to pay for that reservation plus a local hotel I just dont see the savings being worth it.
It may be if you're hotel is close to the parks and you like EMHs.
I crunched some numbers for a family of four (two children under nine) staying at Caribbean Beach vs staying at Wyndham Bonnet Creek (which is very close to CBR) and sharing a campsite with another family of four. I used the last week of October (our vacation dates) as the dates. i realize you can't get a campsite for Halloween anymore, so I just used the average of the days up until the 31st and mulitplied by seven.
Caribbean Beach Famiiy would pay $2,743.92 which includes 1 room, park tickets for 8 days (I think non-hoppers) and admission to Disney Quest and I think Fantasia Gardens. It also includes Magical Express, park transportation, free parking and EMHs.
Wyndham Bonnet Creek family would pay $2,338.48, broken down as follows:
Two bedroom condo with living room and kitchen: $700/week (estimate)
8-day non-park hoppers: $1,318.48
Cab transportation to and from airport: $110 (estimate)
1/2 campsite at Fort Wilderness for week: $210
($59.63/night for tent site, multiplied by seven and divided by two)
As well as the increased space, the WBC family would get everything the Caribbean Beach Family would get except Disney Quest, Fantasia Gardens and the Magical Express video. And it's $400 cheaper.
I compared CBR to WBC because they're right next to each other. It might be an apples to oranges comparison since CBR is a one bedroom hotel, and WBC is a two bedroom condo. The comparison might be greater if you compare WBC to a villa such as Beach Club or AK.
Would I rent out a campsite just for the parking and the EMH? Nope. I just think it's wrong.
Would I rent out a campsite to experience the Fort? One of these days I want to. But this trip, we're staying at Wyndham Bonnet Creek.
With the $15/day parking, and without the EMH.
