Are there lockers? I might need to store some items until I return.

No, not that I'm aware of

1] Check with local... • YMCA/YWCA/athletic complexes, • post office/UPS/other shipping services, • storage facilities, • malls/theme parks First, ask if you must be a member or official visitor, how long you can leave something in a locker, what you would need to do. Second, tell them the flat out truth and beg for an exception and offer to pay something. Third, allow sufficient time to get there to put stuff in the locker etc and then go on to the airport. 2] Package the stuff and mail it to yourself. Inform your local post office you will be out of town and ask your mail be held. Voila, the post office will be holding the packages for you. Make sure you follow all USPS rules and consider insurance as well aa requiring a signature upon delivery. Ask your neighbor if you can list their address as the address of origin, just in case it gets returned to sender. Make sure you have things prepped to package/ mail, know where to take the packag, and reserve time to do it.
