Another shameless post, as I am selling my Cameleon on the forum (Family Classifieds), but I love the Cameleon. I used it on buses/ trains nearly every day and never once had a problem, although I do get on the back doors of the bus. I've never noticed it being wide, but then there are so many double buggies around here I think most single buggies look compact! I think babies/ toddlers just look sooo comfy in the Cameleon! Both kids were in the bassinet for 5-6 mths, with plenty of room, a proper mattress and totally flat (which is advised until 6mths). They have always slept really well in this buggy as its spacious and goes flat even in toddler mode (not sure if the Bee does this too). The toddler seat is a good size - still plenty of room for my 3 year old who is desperate to oust her little bro - I know people whose little ones were uncomfortable in the Bee seat even 6 months before this age. I also think it works really nicely with the great Lascal buggy board, still feeling sturdy and (I found) still manoeuvring (sp?) fine.
