What I did on my winter vacation
We just returned from a ten-day trip to Puerto Rico. The weather was perfect--sunny and in the 80s during the day and cool at night. We did the usual tourist things: hiking in the rainforest, visiting the beaches, observing the Observatory, relaxing by the pool, walking around Old San Juan, kayaking to the biobay, and snorkeling.
We stayed at a small cottage called La Casita, which is part of Villa Sevilla (four different houses you can stay in). It was in a good location to explore both the San Juan area and the east side of the island. If we ever go back to Puerto Rico, we will most likely stay at Villa Sevilla again.
Overall it was a great trip. We had a quiet and comfortable place to stay, met friendly people, got an inexpensive rental car, ate some local food, won money in the casino, saw lots of flora and fauna, got lost only twice, and had uneventful flights (for free too!).
