I am going to mail a package down to SSR for our trip on 7/15. I am going to be using the Owner's Locker after that so there is no mailing back involved. ANYWAY...if I mail it THIS Friday will it make it there by 7/15? Is mail delivered to the resort directly? I want it to be there by Friday 7/13 so I can call and check on it? Any suggestions about which way to mail it? I am going to try and get tracking. Should I use the Post Office or something else??
