<p>S and friend are traveling from Ohio to Miami for Feb. break to visit my parents and siblings who all live in area. They will be staying w/ my parents, who will keep strict eye, but probably going to beach on their own during the day. Any ideas, beyond beach, for safe but fun things 18 yr olds can do in Miami / UM area, esp if they venture out on their own in evening? Thanks for any suggestions…</p>
