Hello Brenda!
Welcome to planDisney! This is a great question as many Guests, especially those heading east, will check out of their resort and spend the day enjoying the parks before a later flight home.
Guests staying at
Disney’s Grand Californian Hotel & Spa can have their luggage held for them on the day of check-out. But if I am understanding your question correctly, it doesn’t sound like you are booked at Disney's Grand Californian, but an alternate hotel. If this is the case, you would not be able to use bell services at the Disney's Grand Californian since you would not be a registered hotel Guest. You mentioned a “hotel across the street.” If you are staying at
Disney’s Paradise Pier Hotel, they also offer the ability to hold your baggage for you on check-out day. If you are staying at a non-Disney hotel in the Anaheim area, I would recommend you call that hotel to ask about their policy for their registered guests.
Another option would be to consider a
locker rental. My fellow Panelist, Anabel did some research on these lockers a few years ago and has some
great information in this answer. If you think your bags will fit in these size lockers, you'd have another option for your departure day.
I hope this helps with your planning for check-out day, Brenda. Wishing you a magical visit to the
Disneyland Resort!- Kate
