Hiya Nicole!
Welcome to planDisney! You are combining two of my favorite resorts in what sounds like a magical vacation.
Saratoga Springs is our go-to when we stay on property. It is so conveniently located next to
Disney Springs, and the spacious villas allow everyone to have a bit of space. Then
Hilton Head is just special. The resort has a very different vibe from the World's resorts. Everything is tranquil and calm with a bit of a magnolia scent.
I love that you are trying to make your life easier by bringing your refillable mugs from one resort to another. Unfortunately, mugs are linked to the location (ie, the World,
the Land, or Aulani), so your Saratoga ones will not work at a resort outside the World.
But! You have a couple of options. You can purchase new mugs when you arrive in
Hilton Head, or you can bring your Saratoga mugs with you and use them in your villa and when you head out to the beach or other activities. (I've been known to throw a Disney mug filled with iced tea into my baseball bag!).
Nicole, when you visit, take an evening stroll along the docks. There is also a fantastic ice cream shop across the marina to top off your night. If you have any other questions, you know where to find us. Have a fabulous vacation!
