I found an article about the new strollers. Are they really more like bike trailer type strollers? I really liked the older version and the old prices too. We are really not sure what to do. We have a 4 year old and a 5 almost 6 year old and we will be there in late Aug. I am thinking they will both need a break from walking at some point. My 5 almost 6 year old is 50 pounds so an umbrella stroller won't work.
