I know this has nothing to do with the original post and not sure that my thought counts but last year I had a 8 year old and 3 year old and while my 8 year old is old enough to walk there were times I made him ride in the rented double stroller...sometimes the crowds are way to thick and at night I am just too paranoied he might get lost...In my world sometimes safety and sanity take priority over what others think...my thought on the orginal post bring a carrier and bring your double stroller if it doesnt work leave the stroller in the room and rent one....Good Luck and have Fun
