We did the drive last week - there's a toll on the I90 east in Buffalo, you grab a card at the first booth, then pay before you leave the State, I think it was about $3.25. 2 tolls in the Virginias, $2.00 and 40 cents (you need change for the 40 cent, I popped in 2 quarters -US only), then nothing until the I4 in Florida, used to be 2 toll booths but one is closed for construction so you pay a total of $3.50 for both. If you take the 417 toll around the I4 it's about $8. You don't need exact change, however if you take some of the other toll roads near Orlando, like the 429, you need exact change (US, CND won't work).
