We stayed over NYE 2013 with our 1 year old son, and had a wonderful time! The hotel is in an amazing location and is very well kept. We were upgraded to suite which had an amazing view, and was wonderful for the baby. We did not eat at any of the restaurants or bars at the hotel, but they looked fine.
Although no Miami beach hotels are IDEAL on NYE with a baby, this one was great, and we'd def do it again!
