Visitor Visa - B2

My appointment will be next week in Cairo, Egypt, and I managed to collect all supporting documents required. I plan on visiting 3 states for tourism only, and attending a concert or two at Vegas.

However, after reading many experiences here I would like to know what would be the perfect response for some questions regarding my case.

I am an undergraduate at a dentistry university here who's in second year out of five and I have a transcript with excellent GPA, which would show that I do not want to lose it by staying in USA and a letter from the university, my Mother and Sister live in Egypt while my Father is in Kuwait, and no relatives whatsoever in USA, plus we live in a house owned by my Father, so are those social ties enough to convince them?

I also travel about 2 times yearly to Kuwait for the past 15 years, have an Indian visa which I did not use and a Bulgarian visa which has a stamp of entry and departure.

I will submit my parents' bank statements and in addition my Father made a deposit of a sum of money to my bank account, which I shall submit too, so I'm planning to say that this deposited money in my account will be used while I'm in USA, which is the truth, so is that correct? In addition I'll submit my supplementary credit card. The amount of cash present is thankfully more than enough whenever I ask anyone, so I hope that I covered this point well.

I have airline bookings, and hotels too for the intended states. I also have a ticket for a show in Vegas that I purchased online, which I may bring it with me to further proof that I intend to go on tourism solely. I may write an itinerary too, or is it not needed?

Regarding the questions, I shall travel during my midyear vacation which is 2 weeks long, and alone, so I expect being asked the following:
1) Why during this time period?
    I shall answer that this is the only vacation when I'm free, and I'm not free during Summer vacation due to dental training

2) Why alone?
    I shall answer that this is due to my Father being busy at Kuwait, and my friends who have a US visa aren't planning a trip to USA during this time

3) Who is financing it?
    I shall state that my father shall pay the tickets and hotels prices, while I shall cover my expenses there with the money he deposited in my bank account

Are those good answers or will they not believe me? In all honesty those are the reasons and I did not make that up for them to gain acceptance.

Finally, as this is something that is really scaring me, should I submit the documents directly when I talk about any reason? For example when I mention college should I submit my letter and transcript? When I get asked about costs should I submit the bank statements? Will this come off as desperate or will the VO think I'm just well prepared and organized?

Thank you in advance! Sorry for the long post!
