One of the items I discussed with volunteers the other night at the Seattle Center public meeting specific to this first date notion, really it's the notion of allowing people to just "be" however they choose. Right now, Seattle Center seems to be primarily a place to do stuff. Whether it's seeing a show, attending an event, or the like, it does not seem to be a place that fosters the notion of just "being" present in the place at a given time. I suggested that it might be worthwhile to consider fostering this notion of just being. Also I suggested that it would be interesting to allow for all sorts of "user flows" from being to doing.
An example of one scenario for a first date at the Center would involve people who wish to see a paid performance (at the Intiman, Rep, etc). They could first go to the Center and walk through any number of interesting paths on the campus. They could stick to the pre-made paths connecting buildings, or they could forge their own path that uses some of the well-traveled ones, and some not so well travelled. Additionally, they could sit by the fountain to watch mini-Bellagioesque shows, or they could wander by the skate park to watch people perform gravity defying tricks. In actuality, there's any number of things the would be first daters could see at the Center. They don't have to "do" much, but rather it's being present with others in this shared space at the Center. If they got a little hungry or thirsty prior to the show, they could pop into any number of restaurants that meet budgets (financial or time) of all sizes. Perhaps a cafe could be at the Intiman courtyard? Afterwards, they would attend their ticketed performance. The evening at the Center could be finished off at a little desert place for coffee, munchies, or drinks where they could further engage about the performance they just saw.
Of course, this is just one way in which a "first date" could be at Seattle Center. honestly, I'm not the best to ask as it's been awhile since I've had a first date :P Others feel free to chime in.
