Hello Moores:
No, like others have said it will probably be too hot to be in your sleeping bags. This is what we have done; take an old twin or double sheet, fold it in half and sew it across the bottom and about 2/3 the way up the side. This forms an insert for your bag. The sheet is alot easier to clean than a sleeping bag. When it is hot just sleep in the sheet and your bag is just extra padding. If it is cold (like up here in Canada, eh!) that little sheet actually adds a lot of warmth.
Also, we are travelling from London pulling a pop-up and will be at FW Sept.29 to Oct.4 hopefully in the 1500 loop. I assume you will likely be in 1500 too. Maybe see you there. Can't be too many Ontario licence plates in one loop.
Pete.
