ok in yet another dilemma - we have booked a hire hire with alamo through the brits guide discount - great price. now then do i book a car seat for our DD just under 3 - but tall and currently in a first stage booster seat. the cost is $70. some people we have met at WDW have taken a car seat and not been charged by the airline (this was in addition to a stroller). what is your experience, do you take your own and if so have you had to pay for this? or do you go with the hire company and if so are the booster seats good? thanks Catrin
