One additional note, it does vary slightly where you buy it from. IE where the hotel vouchers are valid and even the free buffet coupon may vary. I also bought mine through Malaysia as the hotel voucher was good at the Malaysia hiltons and Phuket.
THe Restaurant benifits are the same regardless of which hotel you go through.... But there are some COUPONS that are tied to "Country" that you bought it from. IE mine has many for KL Sentral, doubletree ect.
The free night and free buffet made it a no brainer for me. If you need the contact for Malaysia, i can send you the person who did mine, as they did a nice job with the comminication. as i wanted the package sent to my office ect....
