Guaranteeing a specific car when renting in the US (Orlando)

[spartridge]

Apologies if this has been done to death before on here, but....

If I must take my family to Disney etc next year, I'm going to get myself something to ease the pain. Quite fancy a hemi so thinking of a Dodge Challenger, probably an R/T.

Problem is, sounds like you get to choose from a 'category' only...so as I understand it from my travel agent I could end up with something else entirely. Any advice on overcoming this? Any specific companies etc?

Ta.

Many thanks - will give it a go
