my vote of the best thing to do in Miami is sta inside and enjoy the heavy duty AC! No joke!
Dont forget to go for chalav yisrael Ice cream in Hollywood (10 min from NMB)
be sure to tak a walk outside- you’ll find all kind of interesting looking creatures. Sounds weird, but if yougo to the canal in NMB at the right time of day and drop bread crumbs… a TON of birds from a different world come around you to get the bread…. mamish a sight!
