I accidentally erase my email from my reservation.. How can I get a copy of my reservation

You can go into your deleted emails or call customer service to have them resend you one. Normally they will contact you prior to your visit. You can get a point of contact that way as well.

If you call the resort, they look it up by the last name that you put the rooms under.

Look in your trash emails

Or look in your trash folder

Call the resort
