TIA, I stayed at the imperial palms a couple of years back. It is right next to Royal palms. The entire two resort area is pretty quiet compared to other resorts I've stayed at. If that is what you are looking for you'll be happy. The pools there are very quiet. Matter a fact, there is only one pool at RP and it is near the center club house. You'll have to make sure you request a building near it. RP goes farther out where there is not a pool, only a play ground and I think there is more road noise and a good walk to the pool. If you like activity you'll end up taking the shuttle to the world which is amazing. It has the most amazing pool I have ever been in and the hotel is beautiful. But the shuttle is a pain and you find yourself waiting for it in your bathing clothes next to guests in business suits. I hope you have a nice time.
