Business Meeting- Take 1 for me

I was asked early this week to be the onsite coordinator of a Quarterly business meeting that will take place in Tulsa, OK from the 18-21 of Oct. I was quite nervous to accept but very excited about the possibilities this could have for me. I will basically be the "point-man" at the event, working with the Hotel staff and Caterers to make sure this event goes off without a hitch. Right now a woman that formerly worked for my company is handling all of the planning and details. She is going to send me a book of information this next week that has everything I will need to know, and then some I believe. I am renting a car and driving about 2 hrs. to get there on Tuesday the 18th by 11am for a meeting with the Hotel to meet everyone I will be working with all week. I then will be required to be at least 1 hr early to every meeting room to make sure it is set-up and ready to go(approximately 7AM) then spend the entire day overseeing the preparation of the upcoming meetings and evening events. I will probably make it to bed around 11PM each night. So, I will be really tired at the end of the week, and then get to drive myself home 2hrs. Don't take me wrong here, I am not complaining about the responsibility I will have just preparing myself for the long and exhausting week. Please pray for me that no matter what happens, I will be able to be confident and handle it! By the way this is my first business meeting trip.
