From NYC, before catching a Carnival Cruise in San Juan, my family and I would like to tour PR the best way we can in only 4 days. I intend to rent a car from the airport and after a few hours of rest at a local hotel near by, set out to Mayaguez by passing through Arecibo. Stoping in Arecibo for about 2 hours then continue to Mayaguez then check in. After spending the rest of the afternoon, the evening and part of the morning, we will then set out to Ponce and check in a hotel till the next day. Upon leaving Ponce early Sat morning by 9 am, we will drive back to San Juan. check in at a hotel, visit a local SDA church there. relax in the afternoon and evening(pool and beach) then check out on Sunday by 11 am. After leaving the hotel. I would like to see Old San Juan for a couple of hours then head to the airport and return the car, where a shutle bus will bring us to the ship. Google Driving directions has given 4hrs and 16 minutes as total driving hours, however, I am desperate for some experts advices given that this is our first trip and we would likre to make the most of it. Is this plan sounds doable or could it be very exhaustive for a family of five. Two adults and 3 kids. Thank You in advance for helping.
