Thanks for the replies and encouragement.

We're flying with Virgin at 3pm - pity they didn't have airport strollers avail. Would make life heaps easier!

LS - DS2 is only 10 months so he isn't the problem in terms of keeping him amused, in check etc - it's more the logistics of not having anyone on hand to hold him while I'm in the loo etc. In my madder moments of imagining the worst, I wondered if I could shanghi a Virgin employee to hold DS2 while I popped into the loo. Hmmm. If only!!!!
