I HIGHLY recommend it. We have done it the last 2 trips and it is worth every penny. It is $30 per person but if you have at least 6 people it is $25. There are showers, clean restrooms, a business center, free drinks (alcoholic and non-alcoholic) and free snacks. You can even get a massage if you like.
If you don't want to eat the free sandwiches and snacks they provide you can order from Bobsled Cafe and they will deliver it to you in your room. (This is not free)
They watch your flight for you and will come get you when it is time to go. Both times our flights were running late and they came to inform us and told us they would be back when we needed to leave. It is nice to not have to worry.
There are a few different large rooms with large flat screen tv's, couches to lay on and chairs with ottomans. Last trip there were 6 of us and they gave us an entire room for just us to hang out.
They put you in a seperate line and rush you through customs. It was quick and painless both times. I think from the time we arrived at the airport and checked in, customs, etc. We were in the room within 30 minutes.
Let me see if I can upload a pic... I'm a newb here
