Campus Visit: How to be excited without looking like an idiot?

[Grev]

Here's my situation, though I have a feeling I'm not totally alone in this (?):

 

I got accepted to my top choice school a couple weeks ago.  The school (or at least my department) doesn't have an open house or official visit day, so I contacted my POI to see about setting up a visit to the campus.  My POI has been very enthusiastic, and friendly (part of why this is my top choice), and she suggested I come out to attend a seminar the department is hosting in my field.  The seminar sounded generally interesting, and I tentatively agreed to the dates.

 

Turns out a few of the big names in my field are going to be there, and she's invited me to also join an informal dinner with the presenters (and a few faculty and grad students) at her home afterwords as well.

 

I'm genuinely excited and flattered to be included in this, but every time I try and write a "Thank you OF COURSE I WILL COME OH MY GOSH!" email I feel like a total fangirling dork

 

Anyone have any tips on how to show you're excited and very positive without coming off totally uncool?  Or is it already a lost cause?

 

 

PS: Also, what does one WEAR to something like this? Business casual, or a little dressier?

Just write that you are looking forward to meeting the faculty and students and thank her for the dinner invitation. Short, simple, and sweet always works best.

 

Business casual is pretty standard, I think...anything dressier than that would be too much.
