To stay cool in a hotel bed, take your own sheet and dump the duvet | Brief letters

I suggest that David Bauckham (Letters, 25 May) takes a suitable sheet on his travels, in case the duvet cover in his hotel room can’t be removed and used as a sheet. I usually take a lightweight shower handset and hose to temporarily replace the fixed shower heads used in so many hotels.

• Re David Bauckham’s letter, I invested in a wool-filled duvet earlier this year. It has kept me warm during the cold nights and I haven’t overheated on the couple of warm nights that we have had so far this year, so I am hoping that I have solved the problem.
