I can't comment too much on video poker as I never play machines. There are plenty of people here who should be able to offer you better advice. That being said...

- call reservations
- ask them to transfer you to VIP services
- ask that person if they can make a reservation for you at the casino rate

If you gamble while you're there (doesn't have to be an outrageous sum, but at least a respectable amount), ask a casino host to see what they can comp from your guestroom account (charge everything to your room during your stay).

My biggest general advice is that it can't hurt to ask. They'll look at the computer and see if you qualify. If so, they'll be happy to comp you. If not, they'll probably say no. If they say no, ask them what kind of further play you need so you can get a better idea of what to expect in the future. You should start to receive offers in the mail from them after a couple of visits.

As to your specific question, "Do I go back?" My answer is, if you like it there and have a good time, by all means yes. If you want to try someplace new, give it a go. Keep in mind the higher end properties are tighter with the comps. Of course, that shouldn't be the primary factor in your decision.
