If you buy a multi-day park pass directly online, Universal's site says you get a $150 coupon book. It only gave a very, very brief snip on what is in the coupon book. We do not absolutely need the 2 day 2 park pass and can do just fine with 2 qty one day park passes that are about $180 less for our family of 4 than the 2 day 2 park passes. Just trying to see if that coupon book could tilt us over to the multi-day option. What are the dining and merchandise discounts offered?
