Dolphin Swim at Ocean World in Amber Cove, DR

[teacher1977]

We have signed up for the Dolphin Swim at Ocean WOrld in Amber Cove, DR and I am wondering if anyone who has already done this excursion could give us some information and any tips that might be helpful.  I would like to know if there are lockers and changing rooms available for us to leave a change of clothing, back packs, eye glasses, etc.  Are they secure?  Since the excursion indicates no jewelry or eye glasses in the water with the dolphins we will need to leave these items somewhere and I know that I will want to change out of a wet swim suit.  Any inofmation you could provide would be most helpful.  Thanks!
