We will be staying in Old San Juan at the El Convento three nights in a little more than two weeks. We want to do the biobay tour on Vieques the second night we are there. Because we also want to visit the rainforest that day, I was thinking it made the most sense to rent a car from Old San Juan, use it for the day to explore, then drive out to the dock to take the biobay tour in Vieques. When we got back, we would drive back to Old San Juan, use the El Convento valet to park the car ($20 bucks they said) and return it the next morning.
Does this plan sound ok? Do you think the drive back at night is safe? We are used to driving in the city as we come from the San Francisco area. What should we be aware of when coming back that late at night?
Thanks so much!
