We docked at the downtown pier and we used to go to a hotel near the pier....if you turn left at the end of the pier it was only a block or 2 away, right on the water, don't remember what it was called but we called it the "big orange hotel", you really can't miss it.....
Can't remember the name of the beach we sometimes went to but I think it was San Francisco beach or something like that....Sorry I can't be of more help, will let you know if I can think of it.
Thanks Ali. Actually we have been to the "orange hotel" in July...but it was to rocky for my 11 year old...so we caught a taxi to Playa Azul (hope I spelled it right). No charge, beach is small but very nice. About $24 round trip for all 4 of us. (And they make great margaritias!) Again, a nice place, but we thought we would try something larger.
The big orange hotel is Plaza Las Glorias. Not much beach but a real nice pool. A great beach at Mezcalito's on the other side of the island, right at the end of the long straight stretch of road from town across the island. Another one on the other side that is nice is what we used to call the Donkey Bar because there is always a donkey there. It is the one in the south towards the lighthouse with the hammocks.
