Welcome to planDisney, Rocio! I'm so glad to answer a question for a fellow Texan today.
Building your own Astromech unit at
Droid Depot is going to be such a fun experience on your upcoming trip to Batuu. The First Order is currently monitoring all Droid activity in and out of
Black Spire Outpost, so it cannot be sent back to your
Disney Resorts Collection hotel. There is, however, a secure shipping route protected by the Resistance to send cargo from Batuu to your home, so if you want to have your new sidekick sent back to your doorstep, someone will be able to help you out with that when you check out at Droid Depot.
You also have the option of
renting a locker to store your Droid while you're enjoying the rest of your day at
Disney's Hollywood Studios. Lockers are self-serve and are located at Oscar's Super Service, which is right at the front of the Theme Park near the entrance. Lockers are subject to availability on a first-come, first-served basis so you may want to consider renting your locker on the way into the Theme Park in the morning.
Have a magical day, Rocio, and may the Force be with you!
