Dude, I'm not even gonna be in town. How are you possibly going to disappoint me? :-)

Everybody knows you're on holiday. Schedule things so you have something to look forward to, but realize that everyone is going to be overjoyed just to see you, and you don't need to shag like a trained monkey.

Except maybe for that video bit.

Deep breath. Relax. It's San Francisco in raging hot September. It'll be fun. Two weeks is practically forever.
