Theses prices make Disney Hotels look value for money. Who gonna pay over £1000 for a family of 4 for 2 days in the park and 1 night sleep.
The standard lodges are the same price as Splash Landings. Around £150 per night (weekends more) and a Family of 4 could sleep and have park access for under £500.
The treehouses are very expensive and I wouldn't pay around £700 given that the Raddle Inn cabins are around £200. But there is a limited number of tree houses, they sleep up to 8 and look like they will be finished to a high standard.
