We were there in November and it was a nice day.
You'll need to take a taxi from the pier which will cost about $16.00.
Entry to the park is free and there is plenty of shade. Food and drinks are
readily available and the prices are good.
There are 2 rooms for massages and I had a great one for about $35.00,
and there is a fresh water pool, if I recall. Serving people were very nice.
So, I highly recommend the beach area...... Stan
