I'm not sure why you're worried about using them after the price increase. I have Connections vouchers as well as some other vouchers that came with my tickets. There is a certificate number and expiration date, but they're like any gift certificate. There is no issue date. Think about the people who booked packages that include all their meals. Let's say someone made final payment and a week later the restaurants raised their prices. Their package is paid in full, and they aren't going to have to pay any surchage at the restaurant. The only stipulations on the coupon is locations (listed on the back), whether it's lunch or breakfast, what is included, and that alcohol, souvenier drink mugs, and room service are not included. It does NOT say valid for a breakfast up to x amount of dollars.
