Welcome to planDisney, Fran! Thanks so much for coming to us with your question today.
I love spending the day at
Disney Springs, so I definitely understand why you'd want to head straight there as soon as your plane lands. You can bring your luggage with you to Disney Springs, but there is nowhere to store it so you will have to keep it with you. You likely won't be able to bring it with you to any stores or restaurants, so you may need to split up your party so someone can stay with your bags at all times.
If it is at all possible, I heartily recommend stopping at your
Disney Resorts Collection Hotel first so you can store your luggage with
Bell Services. They will hold onto your bags for you and you can pick them up when your room is ready. Even if you aren't staying on Disney property, your off-site hotel will also probably happily store your bags for you until your check-in time. That way, you don't have to worry about wheeling your bags around Disney Springs with you!
I hope this answers your question, Fran, and please let us know if there's anything else we can do to help you plan your magical vacation.
