I believe Magic Strollers is the only company that does not charge you for the rental until 14 days prior to the first day of your reservation. Other stroller companies do charge you at the time of reservation... Mousesavers.com recommends Magic Strollers over other stroller rental companies. I have never used these companies before and I don't like the idea of paying for my rental months prior to my vacation. so I now have a reservation for a double GT with Magic Strollers and will see if I can get a cheaper one from Kingdom or Orlando after I have made my final payment to Disney.... If I find a cheaper one, then I will cancel Magic... It's a $10 saving for me, not 40 like yours... but still $10..
