In the States everybody is so concerned about liability.... We tried to store at Hertz (where we dropped the rental); no storage facility, no luck. Try a hotel; I tried several, if you are not a guest then they are not allowed. I tried the Information Centre; no luck, they had some bad experiences.... in the past. But they could not realy help me any further. One advise: try the Greyhound Bus Center. And yes! there you can store your luggage. Even my somewhat bigger suitcase. The lockers are somewhat small but high and deep enough. First 3 hours is to be paid for; $ 3 and after that a dollar for an extra hour.
Standing 72'' tall and just 12'' wide, this single-tier locker brings space-conscious storage to bedrooms, break rooms, and beyond. This design is awash in a crisp white finish and sports brushed nickel hardware – including a convenient double hook for coats and bags. On the front, you’ll find a chrome-plated nameplate and latch (locks not included). This product comes backed by a five-year manufacturer warranty. To clean, simply wipe down with a damp cloth.
