Have any of you used Priceline for Rental Car? I need assistance, we are planning our trip to Vegas for April, there will now be 8 of us, so yeah we are looking into a mini van, ugh! I know lol! So the cost would be around $600, I was told about Priceline which I've never used. we put a bid in, we are able to save about $300!! for 5 days on the rental. The companies came up, all here, except for one called Sixt (I may have spelling wrong) we do not have here, what would happen, if it came up with this company? and would I be guaranteed the vehicle I requested, as it says no cancellations? I've been reading stories online that says pricelines class of cars/vehicles aren't what the rentals say they are, I hope someone can give me assistance. TIA!
