Lucky Dragon Match Promo

Doing my pre-trip search for new player promotions. ACG's 'Vegas Values' for Feb mentions a Lucky Dragon Promo for doubling match play coupons. Has anyone used this offer? Is it limited to 1/player, 1/day, etc? I have a handful of them from the ACG guide that I'd love to take there. Does it have to be a vegas casino? Also the LD website mentions a couple other promos, including up to $888 for new players, is this a typical spin to win and get $5 type deal?
