My advice is to take it anyways. If you need it, you'll have it and you can always leave it with someone who can use it in Jamaica. St. Anthony's would be a possible donation place?? (Just thinking...)
Two years ago, I took my wheelchair down to Accompong Town and did not need it. Today, it is available for anyone who does in the community and comes in quite handy. I did the same with my walker last year.
After spending almost 3 years in a wheelchair, I have a good deal of sympathy for people who need one and can't afford it.
Just my opinion.
