We've been to BB a few times. This last time we brought my 82 yo grandma...we wanted to find some shade!!
As you first walk in, and head towards the wave pool...off to the left (looking towards the pool) there are some "deck" areas that a fully shaded. They have a few lounge chairs and a table! This was the *best* spot. There were a few of these "decks" along this walk way, and we over looked the "lazy river" (forget what its called). Also, there are umbrellas on the beach, and other shaded areas around the back of the park.
