Do you like them for use in the parks? I'm considering them for 4 & 6 year olds for heavy use for 1 year (annual pass). Might consider it for use at 'other than MK' parks where I don't plan on using monorail if its size gets in the way. Don't plan on using disney buses much. They weigh too much for umbrellas and I don't want to rent. I'm mostly interested in which type to get of if there is another brand I should consider. The Instep, Schwinn and Safetech double strollers I am most interested in seem to be out of stock from suppliers including ebay. Thanks for any input/advice you might have. I can't find them locally to test drive so will rely on input from others! Thanks again.
