It was almost 12 months before we went away for a break. We booked an adapted room with Premier Inn (chessington) and it was really good, enough room to wheel around, easy to transfer onto the shower seat. All was good. Then in December we stayed at an adapted room in a travel lodge in Ashford (close to eurotunnel) and it was not very accessible, no roll in shower, it had a bath. I should have been really specific when asking for an adapted room. Next time I will ask a lot more questions when booking a room to ensure that it suitable.
You need to be a lot more prepared and plan a lot more, where are you going to stop? Does it have disabled toilets ? Is your room fully accessible? Roll in shower, enough room to park your wheelchair next to the toilet? Is it a sensible height? Disabled parking close to the hotel? Height of the bed so you can transfer across easily
