I've stayed here 4 times over the past 6 months. While the shuttle is free, it's incredibly slow. The last shuttle I waited on took nearly 45 minutes to arrive.
That said and as a Diamond, I've been treated well there. 2 waters in the room (each visit) and an upgrade to a 1 Bedroom Corner Suite.
In both cases, this was merely a 1 night stopover place to sleep so I was quite happy. If I wanted to spend more time in Vancouver, i'd be staying downtown.
