Minivan upgrade success anyone?

I'm headed out in July with 2 other couples and we're trying to rent a minivan for the week but can't get anything less than $500. Instead we got two City Special mid-size from Dollar for $110 ea.

Has anyone tried to upgrade in the garage to a minivan with any success? I'm figuring a $50 bill would give us a shot at one but am curious if anyone has tried it.

 

I've gotten one before when using the Lock-Low-and-go. I've found they are very easy-going down in the garage. I have dollar express and have on a few occasions not liked the condition the car they initially gave me was in and just asked "Hey, what about this car over here, can I do that one?" and often the answer is yes.

 

Cash used to be king in the garage. I even got an instant van upgrade at the counter once from Dollar in San Diego. Doesn't seem to be the case any more.

 

Thanks. I'll give it shot and report back.

 

Last year a $20 tip in the garage upgraded me from a minivan to a tahoe at Alamo. They were trying to charge a little over 200 if i paid for the upgrade.
