Hi Jeff, I will try to answer your questions.
1.If you are only coming to Greg's on Friday, then it is just $12.00. And yes, you may have all the coffee you want.LOL If you decide to do the entire event then it is just a total of $65.00 which includes dinner on Friday night.
2.The room is $89.00 a night.
3. Yes it is fine to arrive on Friday, You have the times correct. And I would bet that there will be someone around a bit earlier as well.
Can't wait to see you as well. It is going to be so much fun, why not try and plan to do the entire event.
