My first date was similar to your situation as it was with someone I met online. She insisted that we go out and I agreed. I didn't have a car at the time so a couple of her friends drove her to pick me up. It was awkward as to be expected from a first date. She was more comfortable because her friends were there but for me it just felt weird lol. Anyways, her and her friends made the plans and it wasn't a terrible night. Went to a movie and then a haunted house afterwards. Surprisingly, she walked through the place like she owned it. I'd go as far to say she held my hand through it. Fun times. You may get some butterflies but it's normal. Good luck and hope for the best.
