Hilton HHonors has this offer for Cisco employees (In reality its open to all) and if you complete the fourth stay in 2017 the status is then valid until March 2019!
HHonors is one of my favorite hotel loyalty program which gives your lots of additional benefits.
You can earn tons of points and miles and other benefits if you are a HHonors member and you can enjoy below mentioned benefits if you have gold status
- Free breakfast is one of the best benefit of the gold.
- You get access to the executive lounge as well in case you are upgraded to the executive floor.
Note that paid stays, Points + Cash and award stays have all counted towards this four stays required.
