We were planning on taking the night train from Paris to Antibes, but most check-ins are not until the afternoon (air B&B). Is there any place that has luggage lockers in Antibes? (so far think it's a no). Currently waiting to hear back from a few places if we can drop luggage off earlier. Definitely don't want to have luggage with us most of the day. Any suggestions?
There's definitely not in the train station and probably not in the bus station, either, since I find no mention of it. Regular, staffed hotels will normally accept customers' luggage at any time. In the case of the AirBnB, your 8:20 a.m. arrival on the train could coincide with the time that someone else is checking out, in which case the manager might be there. If you want to email the tourist office, their info is at http://www.antibesjuanlespins.com/en/pages/contact-us.
