I perfer upper floors with quiet pool veiw, I stayed on every floor except first (which I have no desire to try )and in every room type and have had every view type and have never experienced a severe noise problem in any of them.
Other things to consider are being close to elevators or not, closer to main resort which makes walk to the marketplace and SAB a little shorter and bus stop. If you will have a car being closer to self parking is nice. Remember it's a small resort so when I say closer I mean a couple of minutes, not a big deal when you consider the walking you'll be doing at the parks.
I'll be there in May also, I hope you enjoy your stay, I've enjoyed every one of mine, and have no regrets about buying there.
