Our family of 5 LOVES the Contemporary Resort - despite what some people think!
The rooms are enormous - and our family (which does have 3!! daughters) had no trouble sharing the bathroom - the toilet has it's own little room - so you can have 1 shower, while another is "resting". The beds are queen size (much nicer than doubles!), and the day bed is a full twin sized bed - very comfy!!
We've stayed there several times, and while we do like the tower better than the wings (Duh!), even the wing rooms (we like the North much better than the South!) are truly magical - the views are great -and the walk to the MK is amazingly easy! I like the decor of the rooms, and the 4th floor Concourse is a little piece of Disney heaven on earth!
We have also stayed at the Poly (nice sized rooms, but we liked the CR better - and our Poly stay was concierge level!), as well as the AKL (only concierge level - since we have 5 - a deluxe concierge room is only slightly more than the deluxe savannah room - and the AKL concierge is out of this world!). Our perfect trip would involve a split stay between the AKL and the CR - best of both worlds - AKL for it's complete immersion into the African savannah theme, and CR for it's complete immersion into Classic Disney & MK! love the monorail!
We have stayed at the All-Stars, and just didn't like it! While it was fine - the walk from the Broadway building to the Main Hall was WAY LONG! One day, my daughter left her park pass in the room - and it was a 1/2 round trip walk to retrieve it! The food courts are extremely busy - and the pools, while nicely themed, are pretty boring for teens and pre-teens! No slide - no deep parts - just a place to get wet. I didn't like the teeny tiny rooms, or the small double beds. I guess I'm spoiled - I like the deluxe life, even when you aren't in the room that much!
