In recent years, I've stayed off-site on most of my trips...
--once in a Marriott timeshare, which was nice but a little on the small side.
--once in a private home we rented from a couple off eBay...it had three bedrooms, two baths, a heated pool, washer and dryer, and everything you could ever need in an accomodation. It was our BEST experience.
--once in Buena Vista Suites, which was good, but again, crowded.
--once in the WDW Swan, which was okay, but very small.
The long and short of my thoughts on Disney are this:
you spend so much of your life with your kids...and you don't get to go on vacation very often. If you want to stay up and have a drink with your hubby after the kids go to bed, you can't do it in a Disney hotel room. And if you want privacy, you can't do it in any of these junior suites. Purchasing more than one hotel room can get really expensive, so my vote for the best value is an area rental home.
Having said that, I have to tell you that in January we're staying at the Hilton at DTD. We've got two rooms this time and are only staying there because we have enough Hilton points to pay for it that way.
Part of the magic of Disney is enjoying the solitude that comes with having a little privacy...and you can't beat the off-site rentals for that experience!
