The twins are 18 months and we're going away to Paris for 19 days. I'll be 28 weeks when we go, my doctor has said it is fine for me to wear a carrier and carry one twin in it if that is what we chose to do, he did say to carry the lighter one though. Vee is 16 pounds and Lottie is 18 pounds. We will be walking a lot, the twins don't really like being in the double pushchair. Would it be easier to take the push chair or the carriers? We will be using the Metro a lot to get around in Paris, would it be difficult using the double pushchair in metro?

This is the push chair we have: http://www.toysrus.co.uk/Babies-R-Us/Travel-and-Pushchairs/Travel-Systems-and-Pushchairs/Twins-and-Tandems/Maclaren-Twin-Techno-Stroller-in-Silver(0069963)
