In the past, I have asked Bell Services to transfer my luggage from one resort to another. If you do not have your own transportation, they will do it for you.
When you have checked into your room at Beach Club Villas, just call Bell Services and they will deliver the luggage to you.
We've done split stays before and just take a cab. We tell them how many people and bags. I would rather spend the few dollars and take our luggage ourselves and hope to get into the next room early. We usually leave the first resort at 9am and head to the next one.
Super simple! Just leave your bags with Bell Services, keeping with you what you need for the parks and enjoy the day! They'll probably tell you about what time to expect your bags at your next resort. When you arrive there, or that time has arrived, just call bell services and they'll bring them.
We've done this many many times and it's worked perfectly every time!
