Trying to make traveling with a wheelchair easier

Here is My Question:
This question is two fold. Are there any stores or senior establishments that will swap transport wheelchairs? We currently have a 19 inch one but need a larger one (22 or 24 inch). The other question would be do you know where to rent that will deliver to a ship? I know special needs at sea does this but the fee is greater than buying a new chair. I am trying to prevent having to initially travel with the chair and luggage, etc. 

Answer:
Without knowing what part of the country you are from, or where the ship is (how far would it need to be shipped), or whether you have purchased or rented the wheelchair you currently have, it is difficult to answer your questions.  We would recommend that you contact a few durable medical equipment dealers.  Some of these dealers in New England are:

Home Care Specialists
113 Neck Rd, Haverhill, MA 01835
(978) 373-7771

Laterno's Pharmacy
349 N Main St, Andover, MA 01810
(978) 475-7779

Hudson Seating and Mobility
470 Wildwood Ave., Ste. 4
Woburn, MA 01801
(781)897-6100

Alternative Care Providers, Inc.
51 Middlesex St., # 103
North Chelmsford, MA 01863
(978)251-7077

We did contact Home Care Specialists on your behalf and they said that if you rented a wheelchair it is likely that the company you rented it from would swap it for a larger size. Alternatively, if you purchased your wheelchair, they would not be able to swap it for a larger size, but if it has been more than 5 years since the purchase, insurance might cover a new one and perhaps they could deliver it to the ship.

I hope this helps and thanks.
