We stayed at RPR 2 weeks after it opened ( scored a $99 rate!) I have to say, it is BEAUTIFUL! The inrtricate wood carvings, open-ness of lobby/orchid garden, very lush. The pool is huge, but no water slide. There is a play area with squirting guns, water buckets etc. for kids to play on. Yes, hot tubs and lots of loungechairs. The one thing I did notice was that there is not a "food court" set up or inexpensive grab/go type place available ( or at least there wasn't when we were there) So sit down meals can get pretty expensive. Also, we dodged it back then, but I beleive there is a daily parking fee. We got to see the plane being put into the bay area when we were there, and you can see the IOA fireworks from the beach area ( just look towards Hulk) Now, we are staying at the Polynesian for our first time next week, and we have been in the lobby several times and have eaten at O'Hanas...so while I can't compare rooms, I can say they are both awesome in lobby areas and details. We had decent customer service at RPR....a glitch or 2, but quickly remedied and to be fair, we expected it since they had JUST opened. DH loves their pool the best of any we've stayed at so far ( Dolphin, WL, CR,CBR,ASMU0 and this trip we are POP/POLY.
I do have to say, since it is considered a "value" at US/IOA///the RPR is by far on deluxe terms. Rooms are a bit dark...wood is dark, but again beautiful. I personally would choose a different resort at WDW if you are set on RPR as your chice at US/IOA....the Contemproray is on the monorail and has HUGE rooms as well and is quite the opposite from both RPR/POLY. We have done a split stay every trip but one ( CBR) to take advantage of experiencing 2 themes. I am a huge fan of the Dolphin also...just love the location and pool/beach. I would not do 2 similar themed resorts, but that is me...look at locations for WDW....If you prefer Epcot location then focus there, if you prefer monorail focus there, or if you prefer colorful look value, and to me, the moderates take you to another "world"...themed after locations.
Have a fun trip, and you gotta love the FOTL access at RPR!
