I don't have experience in dating (never been on a date), but I think something that have to do with some physical activities like hiking, bowling, swimming, pool, paint-balling, working-out together etc...
Besides physical activities, K1 is nice. You might want to have competitions together which is always great.
--Arcade would be nice as well.
Small road trip or a night time cruise. Exploring new areas together.
So yeah, that are some of my ideas I can think of right now.
miniature golf or bowling are some good ideas. My boyfriend and I went bowling the other week, I kicked his butt in the first game lol, second game he beat me by one point.
We plan to play miniature golf some time in the upcoming weeks. :3
Oh and places like paintball and laser tag are good ideas. I can't do those with my man yet because he's a big boy, needs to lose some weight. >.<
Exploring is fun for a date! Climb a small mountain or something, or go hiking as said before. Go to one of those wax museums, like if you have a Madame Tussauds nearby, since they're super fun to take photos in!! I don't know if you have ice-cream farms, but they're great (plus they have fresh ice-cream ~ can't beat that).
If all of that sucks, then karaoke and ice-skating all the way.
Defs do a playground then cause climbing up the stairs to a slide is minimal work for maximum enjoyment of going down a slide. It has to be a school you've never even seen before though or else the thrill of the playground won't be very high since you would've seen it already.
Trust me I love playgrounds, but I've only ever explored them with friends but I'd want a guy to take me to one at night and just hang out there and talk. <3
