We chose the first 4 night adventure after Caribbean Princess had a several week yard period to get a preview of the Caribbean Princess for a later cruise and are very happy we did with using the Medallion. We registered before the cruise date and had our Medallions delivered to our home and embarkation was a breeze. We had no issues with the Medallions during the cruise and we were surprised with what some of the features were with them. The ability to use the directions and use the 2-D feature on the screens helped us find our way around the ship quickly. The entertainment was very good; the Fantastic Journey production show was not very good. The songs were hard to understand and there just seemed to be no sense to the production. The comic was funny and we went to his show in Club Fusion also and it was better in a very small venue vice the theater. The magician was also very good having been on Americas Got Talent a few seasons ago. The food was typical Princess, always good and a great variety. Our one stop was in Cozumel, enough said. We have a 10 day Panama Canal cruise in March 2020 on the Caribbean and are very much looking forward to that cruise after experiencing using the Medallion.
