If you go on a cruise, don't use Carnival.  I don't know if you use a
wheelchair or not... if you do, beware of them.  My family went on a four
day cruise last year to celebrate my grandmother's 70th birthday, and we had
a hideous time with accessibility issues.  The "accessible" room was barely
large enough to turn the chair around in, I couldn't fit into the bathroom,
and there was a step up into the shower.  Once we got out of our room,
though, we had a great time ; )
