When you return and have more time to explore, DO visit both of those Resort Hotels.
The DL Hotel in particular has come neat eye candy that anyone can enjoy inside the various hotel buildings.
Don't miss the massive 'collage' of memorabilia display in the hallway that goes by the functions rooms, and be sure to check out the amazing model of 'Big Thunder Mountain' in the lobby of the 'Frontierland' building.
'Jungle Cruise' figure models can be seen in the lobby of the 'Adventureland' building as well, and don't miss 'Trader Sam's' !
The Grand California has a nice lobby to relax in, with a large roaring fire in the fireplace and a live piano player in the late afternoon.
DTD in Anaheim is indeed a bit more cohesive and 'together' then the Orlando version, in my opinion.
The atmosphere is hip and fun...and the vibe from the crowds is different then in FL.
The shops are mostly high end, but there are some nice distractions....and a huge version of 'World of Disney'.
Knott's Berry Farm is worth a visit.
They just finished revamping/restoring some of their most famous classic attractions and they should be experienced.
Knott's is a fun side trip for a afternoon.
