For starters, you can get 100+ reviews of this Wyndham by plugging in the name of the hotel in the 'Search' box to the upper left.
Personally, if you are considering beach sunbathing, I prefer Ft. Lauderdale to Miami...It's just nicer in my opinion.
Orlando is inland, not on a beach as I'm sure you already know. Of course, there's lots to do in O-Town if you get bored with sunbathing.
Warning: if you haven't been out in the sun before the trip and started your tan, don't plan on sunbathing 'all day' - you WILL burn regardless of the amount of sunscreen you use.
Be sure to use a high SPF sunscreen frequently and start your sun exposure gradually - I've seen lots of fair skinned people "burned to a crisp" because they do not realize or ignore the intensity of the Florida sun in June.
