We booked a handicapped accessible cabin at Ft. Wildeness. It has a roll-in shower but our child cannot sit up. Is there a place to rent shower chairs & other special needs equipment? Or do we need to count on packing his shower chair? Also, are there chest harnesses or additional supports, besides the lap belt, on the airplane wheelchairs that take a passenger to their seat? I've seen them but we haven't used one yet so I don't know what kind of support they provide. This year I anticipate that he will be too large to just carry to his seat. Thanks.
