We have stayed in both Deluxe and Moderates, and for my money it's the Mod's
Here are my thoughts on the Moderates.
CBR - Very spread out, 2 stories, no elevators, Super beautiful grounds, and great themed pool, with a hot tub very nice at the end of a long day, also quite pools which are nice to enjoy in the evening. This resorts does not share buses with other resorts, but there are several bus stops. Double sinks with counter space which is nice with 2 DD's, with a privacy curtain which is very practical, with girls. Food court is good, everyone should be able to find something to eat.
CSR - Again another very spread other resort, this is a convention hotel and for us does have that vibe, not as much Disney theming, Pool is nice but super crowded, not a lot of space, Rooms are nice, just not Disney themed. this for us was the most spread out and hard to get around. This resorts does not share buses with other resorts, Food court for us was awful, not only do you have to compete with other vacationers, you have convention people to deal with and they just will run all over you, also the food choice weren't to our liking.
POFQ - This is a very compact resort, nice pool, really nice grounds and theming, Rooms, 2 sinks with counter space, privacy curtain, only 1 bus stop, most of the time does not share buses with POR, depending on the time of the year something you will, Great food court, also walking distance to POR, so you can use there pool and food court as well about a 10 min. walk along the river. Boat transportation to DTD.
POR - We have not stayed here but used the pool and food court, both are very nice, and the food court has really great salads. Boat to DTD, and at times does share buses with POFQ.
I think your DD's will be happy where ever you stay. Enjoy your trip.
