Adult sleeping bags- a double or 2 x zippable-together?

[miljee]

We currently use a double air bed and a duvet. It's a real fag to lug it around plus a sheet so I'm thinking about getting sleeping bags. We'd want oblong, not mummy-style ones (we have DSs, 6 and 8 so won't be doing any 4 season stuff!). Question- if we buy a double do you get that 'draught down the middle' thing happening? We're both smallish as in 5' 6" apiece but should we get a king size? Or will that just create more gaps for the wind to whistle down? Also as air beds DO get cold at night when we're using a duvet, will a sleeping bag solve that problem as in having padding underneath us? And how small does a double sleeping bag fold down? OR should we get 2 bags that can zip together? But may be collectively more expensive?

We've got sleeping bags which we can either use separately or zip together into a double. Problem with both is that if either one of us wants to go to the loo, it's really difficult to get out without disturbing the other big time (ie on a double air bed you disturb each other a bit anyway). We've now changed to taking our duvet and find it much easier, but put an opened out sleeping bag over the airbed as the first time we took just the duvet, we did find the airbed cold. I have to add that although we've been camping lots of times, we've never gone for more than a long weekend, so perhaps more experienced campers who camp for a week or two at a time will have better advice.

SINGLE KING SIZE SLEEPING BAGS - DO NOT SHARE

sorry, needed to get my point across!!!

We used to go camping with the two sleeping bags that zip together, on an airbed, in the days when I would have followed him to the ends of the earth.
Now he goes camping with a single sleeping bag.. and I am at home in my nice soft double bed.
