CTY929...
Speaking from a personal experience...
My first trip to the beautiful island was last May...and we stayed at the Riu Bambu...which is part of the Riu Complex in Punta Cana...
The Riu Palace is their 5 star hotel...It's incredibly luxurious...the food, service, everything is incredible...
And their Animation team is one of the best I've seen in the whole island...You'll see what I mean when you get there!
Have fun!
