I'm not Bub's nor the AMA nor FIM, but I think I can help here.
1. Yes, I think that's correct.
2. More than just one of the hotel/casinos offer leader prices like that, but yeah, it's a good price. Go ahead and lock it in however you can.
3. I think it's an absolute that to run at Bub's you must be an
A M A member. If you're interested in trying for an F I M record you need to ALSO go through the requirements for that organisation (which entry deadline may have already passed, making the point moot).
4. What's your definition of CISED? Google tells me that it's "Centre for Interdisciplinary Studies in Environment and Development", but I think maybe that's not the definition you've got in mind. ( I did look further down the google page and see some other meanings...)
