Hi! We went a few years ago, Placencia was our absolute favorite, highly recommend. We bought tickets on shore once we got off the ship. They group you together and take you over in shifts. It’s a pretty quick ride over. You would do that regardless if you’ve booked independent plans or just want to walk around town, unless your excursion specifically gives you other instructions. We explored the area, ate at a local restaurant, and relaxed on the most beautiful beach.
We talked to a few people who did not ferry over to Placencia and stayed on the shore and went back to the ship a little early. We used up ALL our time on Placencia, ferried back over, dipped in the pool for all of 10 minutes and then got back on the ship. It was our favorite stop of the whole itinerary. But we also love “off the beaten path” areas.
