There will be some movement, but I certainly wouldn't expect to get a minivan with a top tier company for $100/week like was available in years past. The question is what are you willing to put up with to save money? You can find a small vehicle from an off property rental company for much less than that. I am paying about $300 for a week long rental with a top tier company that allows me to walk right out to the garage. The recommendation is always the same, use
www.autoslash.com book whatever you're comfortable with and then have them track the rental to get any price drops. I have a trip next week that I think it started at just over $400, and ended up at $295.
