Orbitz reservation and InterAmerican Car Rental at MCO

[kenman64]

I just reserved a 15 passengers Van from InterAmerican car rental through Orbitz for a week in august for $370 plus taxes and fees. It the best best I found anywhere. I'd even went to InterAmerican website and reserved the same van and was quoted $499.

Had anyone rented for InterAmerican before?
How are their services?
Are they reliable?

I received confirmation #s from Orbitz for the reservation.

Anyone reserved and booking anything through Orbitz before?
How reliable are they?
Will rental car company honor Orbitz price?

Any inputs would be appreciated. Thanks you
