Leading Hotels of the World owns a group of very select high-end hotels around the world. If you happen to be booking a stay at one of their properties you can get their Leaders Club Membership for free.
Although the basic membership is the lowest tier of paid elite status you'll still get some nice perks including free continental breakfast for two, free internet, welcome gifts, free room upgrades, and extra reward credits and member-only rates.
This paid elite status normally costs $150, but currently the Biltmore Hotel is offering a free membership via a promotion.
If you are interested you can find a full list of their hotels here.
To get your free membership all you need to do is submit this application with your name, address, email address and signature and email to email@example.com.
Since you are just joining you can leave the account number section blank and within 7 business days you should receive your membership number via email.
