We just did this a few weeks ago on SWA. We got to SJU on time and our checked bags came quicker than we have ever gotten them at any major airport. We stayed in the same area at Hotel la Playa. No pool but direct beach access, great restaurant, very friendly staff, remodeled rooms and bathrooms. The only negative for us was the next morning the shower never got hot.

It was a great start to our vacation and I loved walking up and down the beach until sunset that evening.
