Hello! Would appreciate some advice about luggage- after arrival at Heathrow, we'll be staying one night at a hotel in Windsor. We plan to visit Windsor Castle for a day before departing from Windsor Central station by train at 4:00 to go to Bath. Our hotel does not allow us to leave any luggage after check out at 11:00 AM. We'll have carry-on size rolling luggage and another small carry-on bag. Would we be allowed to leave these items in the cloakroom at Windsor while we tour around?
