We were day visitors to the park but enjoyed the layout and how the parking was about a mile from the beach. We walked to the beach in the morning but after a day on the sand & water elected to take the free tram back to the parking lot.
The trams run every hour so you would need to time your beach exit if you want to use the trams. The water had some algae and seaweed but it had rained the night before. We liked the relaxed atmosphere and warm gulf water.
