Another suggestion -- For a little more than $100 we purchased transport chairs for my folks to take them to St. Maarten the last few years. My dad has very little patience and I was worried he would refuse to wait for a chair to be available. I will say that at the airport if you are in your own chair you receive very special care and attention. The service at both JFK and SXM was above and beyond. The chairs came in handy during our stay as well -- less walking, risk of falling, etc. They fold up nicely if you don't use it until your return flight. Just a thought....
