We saw no seaweed on March. It's not the warmest time of year, but was really clean!

I don’t remember there being any issue with seaweed at the time we visited.

I’m a marathon runner. Recently ran the Miami half marathon. I have run the Miami Beach boardwalk many many tines in past 5 years. I personally like to go out early and before the sun rises. For one it’s much cooler but above all lot less people. The boardwalk tends to get busy as the day goes by. So I go out at 6am about 5/6 days a week when I’m down there.

Always walk together. Safety matters. Be safe than sorry

Your best bet would be the hotels on Collins Avenue. Most of them have a back access to the beach and the boardwalk for a nice morning stroll. Also if you want to stay in a shopping area, you need to be close to Lincoln Rd. and the open air strip. There are a few very nice hotels on Collins between 14th and 19th streets. You will have direct access to the beach and the shopping a few steps away. Enjoy it...

Yo siempre me sentí super segura. Pero siempre me quedé hasta el horario que cierran los restaurantes. No sé como será más tarde..

Las personas andan en bicicleta y hay muchos lugares para rentarlas, es fácil de hacerlo

Si se puede hay una parte en donde comienza una pasarela de madera donde se hace más estrecho pero no hay problema, igual es más lindo ir para el lado del puerto y ver salir los cruceros, se rentan bicis y momopatines a motor tb, pero en la mayoria de los hoteles sobre todo los q estan sobre la playa, te dan las bicis gratis en el royal palm me la dieron gratis!

Goggle South Beach Miami maps and check out the area of Collins Ave. The hotel website should tell you if it's located beach front.

Taxi and Uber cost have already been discussed. What I absolutely recommand is to do it! How boring a night entirely spent at the airport, and how exiting to spend some time visiting South Beach, especially Lincoln Road, Espanola Way and Ocean Drive!
