Sometimes you just have to learn the hard way
Booking a hotel can be a stressful experience. You either wade through your guide books or online listings searching for the perfect spot to stay. I personally use the online method via Expedia and Tripadvisor to try and find a place that looks appealing, also free wi-fi. For some of us there is the added challenge of finding a place that also had to meet our accessibility needs. Now of course this is different for everyone. For me it means finding a place that is wheelchair friendly.
Things are not always as they seem
The problem is just like any other information gathered online, things aren't always as they seem. Once you have picked a place out that you feel you want to stay, see if you can get in touch with the hotel directly. Sometimes this is easy other times not so much, especially when language is an issue. For example I booked a hotel in Tel Aviv that seemed wheelchair accessible for all the information I could get online via a travel agent. Then when I contacted the hotel before we traveled to confirm and let them know I was traveling with a wheelchair they told me the hotel was in fact not accessible. After finding someone at the travel agent that spoke Hebrew and a phone conversion later it was determined that yes everything should be just fine. Then we got to the hotel, remember how I said everything is not always as it seem? Well there were elevators (great) but they were quite little (uh oh). My wheelchair is only 21.5 inches wide at the wheels and I just managed to squeeze in. Had my chair been any larger I would have been totally screwed as our room was on the 6th floor and there were no ground floor rooms.
The other reason to contact the hotel directly is some hotels have rooms that are setup to meet the needs of disabled travellers. Staying in a downtown San Francisco hotel the room we were given was much larger and the washroom had grab bars and a shower seat for example. Theis was of course great and made our stay a lot nicer, except for the loud bar across the street. Never forget to pack some ear plugs.
