FullFare, I definitely have to disagree with this point.
Personally I made great use of the hotel upgrade on my trip to London to visit my then girlfriend.
Stayed at the Inter-Continental Hyde Park, very nice hotel and location, and got a great rate... AND I got upgraded to a deluxe room with an option of free full english breakfast for two.
The room upgrade would have been a difference of at least $100 a night AND the full english breakfast for two would have run me $60 a day. For 3 nights, that coupon gave me a savings of $480.
Definitely worth it to me... still have one more coupon and i plan on using it soon.
If anyone wants my car voucher let me know... I'm only 22 and dont qualify for the rentals.
