Hi Lauren!
Thanks so much for your question. Depending on which
Disney Resort Hotel you have chosen,
check in time can be anywhere from 1:00-4:00 PM. I think you are smart to head to the
Parks early so as not to miss one single magical moment there and check in later in the day. You absolutely can drop your bags off at your hotel anytime on your arrival day. As a matter of fact, my family has done this many times and it works great! Simply take your bags to the Bell Desk at your hotel and ask them to hold them for you. They will be safe and sound there until you return for them later. By the way, you may want to stop by the
front desk, as well, and begin the check in process. Be sure they have your cell phone number and that you have requested that they send you a text when your room is ready. That way you know for sure when everything is in place for you to return, complete the check in process, pick up your bags and head to your room. It's a simple as can be!
I'm so glad you stopped by the Disney Parks Moms Panel and I hope you will come back if we can do anything else to assist with your planning.
Have a wonderful day!
