Treat for Mom and Dad

My husband and I are planning to his parents a treat. Well I am thinking about sending them both to a SPA treatment over at the coast and stay for a night there. That would be wonderful because aside from the relaxation they will be getting, both of loves to play at the casino so it is really a package. I am searching for the best package now and so far I've found one. will tell hubby about this and hopefully they will like. They need a break...Hehehe
