We just came back from the Surfcomber where we spent five nights. It was spring break and really crowded. The pool staff always seemed to find us chairs, and we didnt have a problem getting chairs at the beach as well. Food service at the pool was really slow, but I think that was a result of the spring break crowds. Walking to the beach was easy. It is close to all restaurants and Lincoln Road. Staff was great. You can tell it was was an old motel that they refurbished. They had very nice furnishings and a great bed. We had two queen rooms and they were adequate size. It was our first time in South Beach, so I can't compare it to other SoBe properties.
All in all, it was a great experience at the hotel. Not sure, however, that I would bring my kids back to SoBe for spring break. There are other more family friendly places to go for spring break. The focus is definitely on the clubs and nightlife.
