Earliest Alamo rental shuttle leaving the port?

[lisamac]

I've read a lot about shuttle arrival times at the port but can't find any information on shuttle service from the ship to the Alamo store at the conclusion of the cruise. We would like to do the express exit but didn't know how long we may have to wait on shuttle service. I've tried to reach Alamo with no luck! If anyone has info I would appreciate it!

Thanks!
