I've never stayed at Orange Lake though I do know where it is. I have stayed twice at WH in two different townhouses. It is a very nice resort with a huge zero entry free form pool with waterslide and a fountain splash area for kids. There's also a big castle playground for kids, clubhouse with video games, pool tables, ping pong, fitness center, small theatre, store. There's a chipping/putting green, tennis courts etc.
There are 2 and 3 bedroom condos, 3 bedroom townhouses with private 12 by 12 foot splash pools, and 4 - 6 bedroom pool homes with regular size pools. This resort is only 2 years old so all of the homes are new. Each one is privately owned therefore each one is decorated differently with different ammenities. It only takes you 5 min to get to Disney Animal Kingdom and about another 5min to the rest of the Disney parks.
You can't go wrong staying here.
