I use airbed, duvet and pillows for indoor camping. Some people have those very tall air beds so it's like a full-size mattress :) Some also use traditional scout-type campbeds, or travel light with rollmats.

Only warning would be- if you have a bed that takes up a lot of space, get there early!

Usually, when large-scale indoor camping is organised eg in a school at Banbury festival, thee are different rooms, some of which are 'quiet' areas.

In the case of the Swan at Alcester this is the first time we'll be using it, and I believe we'll all be in the one room. Again, get there early to bag a spot to your liking.

Give it a go, Sal- it can be good fun :)
