be very, very, very, wary of Dollar's toll policy
if you opt in at time of pick up, they will bill you for $10 for each of your rental days ($52 cap per
week). To be fair you get unlimited toll usage for that price, but you pay for each day of your rental. For a 3 weeks rental, that's $150 flat fee wether you use tolls or not.
If you don't opt in at time of pick up, and accidentally go through a toll, you'll be charged the $52 per week, as well as a $15 fee for each toll your hit (capped at $90)
so be very, very wary
Alamo is $3.95 per 24hrs you actually use the tolls, + the tolls at Toll by Plate rates.
compared, a 3 weeks rental, where the driver only goes to and from MCO
it will cost $150+ with dollar, and under $15 with alamo
