The problem I am seeing is if they do offer the Xel-Ha tour from Playa, I should get $18 per person returned to me since we aren't taking the ferry from Cozumel, (I've checked on-line and that's how much it costs if you purchase it at the dock). However, the RCCL customer service rep. stated to me yesterday that he had never heard of them doing a partial refund like that. I don't think that is right. So if they don't offer to give me some of my money back or don't offer that tour, I was thinking we might just do it on our own. What is the availablity of getting transportation from the pier? Which is the safest and most reliable? Any recommendations?
