My sister and I are starting to plan a trip to San Juan and Key West for my 35th birthday in April. I did a little research about Puerto Rico and the guidebook (Fodor's) says that to really explore the island, you should rent a car; and they do not recommend driving in San Juan. Because I dislike driving and want to enjoy my vacation, we're thinking of spending 4 nights in Old San Juan only (this seems to be walkable). Then we'd fly to Miami, rent a car, and drive to Key West where we'd spend 2 nights before flying home. Does this sound like a good plan?
We haven't bought plane tickets yet or even looked at hotels. Does anyone have hotel recommendation for Old San Juan and/or Key West?
-Any advice about San Juan from people who've been there? For example, I read about the mosquito problem there and the suggestion to bring DEET.
-It seems that toll roads between Miami and Key West don't accept cash, and rental cars with the SunPass have to pay fees to the rental company for use of the pass. Any way around this?
