The family and I will be driving from Ontario to WDW at the end of February, and I was wondering if it would be worth it to buy one of those $4.99 mini SunPass transponders for the toll booths on the FL turnpike and SR 429. Do these type of things let you get through the toll booths quicker? Do you have to stop to let the scanner pick up the SunPass, or can you drive right through? We do not have highway toll booths here in Canada, so it's not something that I'm familiar with.
