No flaming please - if you have opinions on whether I need one please keep to yourself 
I have just realised I have 5 weeks of holidays on my own with the kids - aged 6, 5 3 - and I don't drive. Can get most places on trains/buses (ie hour ish to get to Brighton etc) but a double would make life so much easier as 5 yr old has a tendency to fall asleep rather a lot. Also to transport all the cr*p we seem to need.
5 and 3 yr olds both weigh 17kg ish - so what are my options? Was thinking probably phil and teds as have had in past, can get cheap and know can fit onto buses - but as haven't had a double for ages anything else I should consider? Will need to be tandem to fit on buses - and pref available for under £200 second hand.
Is there anything?
Cheers
