Absolutely!!
- Guaranteed room when hotel sold out - used this benefit several time and it is very convenient when booking at the last minute.
- Lounge access and free breakfast - very convinient in US properties but especially in properties overseas as their breakfast is much better. Also, cocktails and hors d'oeuvres in the evening (some times even a full dinner buffet).
- 50% points bonus
- amenity gift
These are some of the benefits I really enjoy.
