Hello!
My teenage sons and myself took advantage of Princess's air deviation and flew in a day early. We arrived in Puerto Rico on a Saturday with Sunday's sailing of the Ocean princess. We choose the Caribe Hilton. My opinion of this hotel is nothing but the highest! We were in the garden district, with a balcony that had complete view of the ocean. It seemed the entire floor was dedicated to Ocean Princess passangers, as our only requirement was to have the bags outside the door at 10am. When coming back from a morning sunrise swim (yes, they have a beatiful beach too!), I smiled at all the Princess tagged luggage in the hallway. This hotel also has live music in the open bar area. I will admit the Sunday brunch was a bit pricey (around $20pp). The hotel also has a concierre, and we took advantage of his recommendation for places to eat and choose the Hard Rock Cafe in Old San Juan for Saturday evening's dinner (teenagers).
My suggestion: Stay here if you want continued ambiance, relaxation with music, and strolls around garden districts, sandy beaches, and a great view of the ocean. They also have an old fort next to the hotel (Fort Jeronimo). This place, couldn't have been better.
