We're considering a trip to PR in July. I google'd a bit and saw some intriguing websites about Aquatika, but these forums have since scared me off. My kids are 6 and 8 and love splashing around in pools/beaches. Which places would you recommend? We would like to spend some time in El Yunque and Old San Juan -- but the kids would probably most like the water. Would it be better to spend a few days on the main island and then a few days on Culebrea (or Vieques) -- or just take a ferry over for a day? Thanks for your help.
