I will be writing up a list of hotels and restaurants used during a recent road trip soon.
However I thought I would give a link to those who require luggage for a Morgan.
I own a 2006 Roadster and have found that North Face produced a bag that would fit the parcel shelf. you can get two across the shelf and they will take at least two weeks of clothing and 4 pairs of the wifes shoes.
Understand that the bags are no longer in production but if you can get hold of them they work.
Link as follows:-

this means you will have room for a tool kit and various electrical spares. If you feel the need to wash clothes just put them under the bonnet at the rear to dry out, the engine heat will do the job
