If anyone is a paraplegic or has other problems that prevent them from using their legs, I can recommend a hand cycle tour of The Netherlands. I did it this summer for 9 days with my wife pulling a “buggy” behind her bike that held my wheelchair.
We used Holland Bike Tours led by Emiel Blok. You can find his website at this link: hollandbiketours.com
Emiel put together a custom tour for us and had our luggage delivered to our next destination each day. It was a great trip. All the hotels and B&Bs were very wheelchair friendly. Attached is a few picture of us on the trip.
