I've stayed at HNY, SL, NBC and Cheyenne, as well as Dream Castle, Radisson, Explorers and Kyriad offsite. Hotel New York used to be my favourite but I now prefer Sequoia Lodge - with the HNY looking a little run down the rooms are at least as nice at SL and you can usually save a bit. I love Cheyenne as well! Of the offsite ones I've stayed at, I really like Dream Castle too and would go back there if on a budget.
I'm really really hoping to finally stay at the Disneyland Hotel next year just for a couple of nights for a special birthday....and I guess I should also try the Santa Fe so I could then say I've done them all, but when I went to take a look at it the theme didn't appeal to me. For the same money I'd choose Cheyenne every time because I love the theme (just a taste thing really).
Heading to Sequoia Lodge for the third time in a few weeks, and can't wait to stay Golden Forest.
