I would say give Seasplash a chance to work it out for you. If what they tell you doesn't meet your needs then contact LivingSocial for a refund.

They were very pleasant and helpful to me. I had won a 2 night stay at Seasplash in what was basically just a verbal agreement with Jim so I assumed that due to the circumstances there would be no way I would be able to redeem that, however I emailed Sheryl and she got right back to me saying Congrats and that they would definitely honour it.
So I would say they are working hard to make sure all of their guests and customers are taken care of, which is very nice to see.
