Only stayed at one Wyndham, the MIA Airport and found it to be very nice. They let us check in at 9am (my wife was sick). I booked thru Priceline and got it for 50 bucks and added my Wyndham by request and got an upgrade and free continental breakfast.
Staying at the Wyndham Grand Bay in Miami in September and hear it is a very nice play, plus again got it thru Priceline for just 70 bucks a night.
