My wife and I try to spend our anniversary with mouse every year we can.
We have stayed at Wilderness Lodge many times and it has become our favorite. We love the theme, the music being piped into the lobby, the fireplace, the rocking chairs, the pools and hot tubs. We have found the CM's to be very friendly there as well. We have never had a bad trip at WL.

It has good onsite dining and the Mercantile is a nice shop. Also, has boat to MK (we love riding the boat-we love the horn) and it is a MK resort, which we love as MK is our favorite park!!
If you can get Club Level at WL, it is even better as they spoil you wrotten up there.
We have also had good experience at CBR as well. The resort was very quiet and we had a relaxing vacation there as well. It has a good food court onsite, nice shopping, hammocks on sandy beaches!!

The rooms are the size size (square footage wise) as WL so we had enough space for all our stuff. We were pleasantly surprised at CBR.
I guess it comes down to your preferences and your likes and dislikes. If you want to relax, these 2 resorts are great. I do prefer WL over CBR but both are very relaxing and have a nice theme. Hope this helps!
