A warm welcome to FlyerTalk flyfarfar and congratulations on your upcoming proposal. I love San Francisco and you've done well to choose such a beautiful city. My recommendation would be to suggest to your girlfriend to go for a nice evening drive (assuming you'll be hiring a car) and go across the Golden Gate Bridge and up to the visita overlooking the bridge. The whole of San Francisco is at your feet. That would be a perfect setting for your plan. And don't forget to bring a bottle of bubbly and some glasses to toast. Cheers!
