Hi Sheila – Congrats on your daughter’s graduation! The only real way to see “everything” is to purchase an island tour, either through your cruise line or an independent tour operator. A half-day tour to El Yunque rain forest is very interesting and an easy option. Since your day in San Juan has an all aboard time of probably 2:30 or 3pm, I might suggest a walking tour of Old San Juan and make your way up to El Morro fortress. Maps are available either onboard or at the terminal. You’ll have a chance to see the old city, have a lunch at a café or restaurant, admire the beautifully-kept buildings that line the European style narrow streets, explore the centuries-old fortress and maybe do a little shopping. Shore excursions in San Juan for a half-day will probably be in the $65-100 price range per person, whether through the ship or an independent company. While San Juan has some very beautiful beaches, you won’t have a chance to see much else of the island if you opt for a day at the beach. Aside from a tour to the rain forest, a walk from your ship to the fortress will give you an opportunity to see a beautiful part of the island. If someone has difficulty with mobility, it’s an uphill walk to the fort and an easier downhill walk on the way back. Of course you can always get a taxi from the port to the fort.
Have a wonderful first-time cruise! Thank you for your email.

Hi Carmela,
Thanks for your nice comment. You’ll have a wonderful day in San Juan. If you decide on a self-guided walking tour in Old San Juan, try to allow time to have a drink or snacks (or both!) at El Convento. Bon Voyage!
