I see a reward is 2 buffet passes to Bellagio for 136 K points. I am going solo I was wondering if I could use this pass twice or if it is for 2 people to make 1 visit to the buffet.
You can't use the pass twice - it is one pass that admits two people at the same time. The other person has to be with you when you redeem the pass. If you want to do two buffets for just yourself then you could always get one Bellagio buffet pass and one Aria buffet pass. Aria is a very good buffet (I actually like it better than Bellagio's), and it is close to Bellagio. And the best part is that purchasing two single buffet passes costs a lot less loyalty points than buying one pass that admits two people.
