Hi all,
this short message just to say that XING promotion still works.
I got upgraded even if I haven't yet my Silver card (did someone get it through this promotion?).
As I'm changing my travel patterns now having a GPP Silver card can be useful.
Personally I like the late check-out and, of course, "upgrades" (see under for the exact "wording"). But Late check-out could be already enough.

Do you know if Radisson give late check-out easily?
Last times in Budapest was always paying....but I wasn't silver


I paste here under the benefits they listed to me:
Silver
25% Points Bonus
Late check out
Best Available Room in the category booked
Special Points plus cash offers
Priority full- service Member Services telephone number
- In Europe, the Middle East and Africa, you'll also enjoy the following
Elite membership benefits:

Gold
50% Point Bonus

Well, it seems Gold users still benefit of Weekend extend!
About Silvers, I just need to understand what it means "Best Available Room in the category booked"...it is not exactly an upgrade...just a better room among those in the level I booked.
