The Port of San Juan:
All cruises call at Old San Juan, and it's hard to imagine a better introduction to the island, especially if time is short. From the pier, the old walled city strethces majestically in welcome, and if you've only got a day between stops, it's where you want to be.
Cruises to Puerto Rico:
As to how best to spend your time once you arrive at Old San Juan, remember that time is always at a premium when you step off a cruise ship. If you've only got a day to enjoy San Juan, you'll be well served by taking a walking tour of Old San Juan. Also, make sure you have your San Juan Fun Card, a special promotion specifically for cruise ship passengers arriving in San Juan. The card offers discounts to participating restaurants, hotels, and other businesses.
