I guess it really depends on what you like. I really don't like the idea of P & T's with the second seat being so close to the floor. I don't want a double either as I want to get it into my small boot & get through shop doors. We're looking at these two at the moment:

Both require extra carrycots, but both seats can be parent facing, which is an option I favour. We really need to go and have a look at them to decide which though. Not really got long to sort it either...
Hubby's idea was to keep the travel system we have & put peanut (snap!) in a sling-which is a great idea in theory, until s/he gets to the same size as Poppy, or we have a winter like the last one!
Plus, he's not going to be the one carrying him or her!! So, I shall be dragging him kicking and screaming to a large shop/department store to help choose :lol: xx
