I'll be arriving in Puerto Rico a day before the cruise starts and will stay at a hotel that others in our group will be using. Guess it's not the fanciest hotel, but has beach front and the price is around $80 for the 1 night. We'll share a big taxi to Celebrity Summit.
Last time I was there, we did a walking tour on our own. My sister, her husband, and I had just finished our Summit Cruise. I met Barb, my roomy for Adventure of the Seas, at our hotel. We all took a city bus (50 cents each way) and hiked the ocean front below the fort. We then climbed the big hill and toured through Old Town, stopping for a food break along the way. We ran into others from our group on the bus. Lucky us to be departing for another 7 night cruise the next day:-)
