Lifejackets available at Magens Bay?

Sailing on Adventure of the Seas next month and planning on going to Magens Bay. My two boys are currently taking swimming lessons, but should still wear life vests when in the water. Are they available at the beach, or should I bring my own?

Bring your own as I have not seen any for rent at Magens

We just went to Magen's Bay in May and they did not have life jackets. I was not impressed with the beach. Very crowded, rude people in the shop and you had to drag your beach chair to wherever you wanted to sit. :o
