I'm sure it will be ok! Maybe it's better that you are all meeting in Vegas instead of someone's home anyway, because it will take some of the pressure off.

I know I was nervous when I met Eric's parents but that was only because he said "Well my mom usually doesn't like anyone that I've dated." It turned out she really liked me, and still does! Just be supportive to Alexa since I'm sure you'll both be be nervous (I would be) and I'm sure everything will be fine. Sounds like a fun vacation!
