Welcome back, Linda! There is so much to do in St. Thomas, it's tempting to want to do it all!
The Skyride in St. Thomas opens at 9:00 a.m. and the Butterfly Farm opens at 8:30 a.m. You will certainly have time to enjoy the Skyride to Paradise Point before heading back for your 1:15 adventure. In fact, Disney Cruise Line offers you the option to purchase the same price tickets for the
Skyride with them if you'd like. It's nice to know you have the tickets all set.
I don't know the exact hours for the shopping mall, however since it's a tourist area, I can only imagine that they're open around 8:30 or 9:00 a.m. too.
Have fun planning, Linda!
