Hmm... I have no experience with going on dates. I do have a few ideas though. They are not very exciting ideas, no zip lines or roller coasters or haunted houses. But I believe I am one of the most quietly decadent men I know.
BUDGET:
This would involve a large pack of tater logs from a local supermarket deli. They get big potatoes from the store's produce section, cut them in quarters lengthwise, coat them with breading and fry them. They are beyond delicious. I would get a 25-pack of them.
The date would consist of sitting on the couch all night, with a lot of tater logs and a lot of little bowls of different kinds of dips. Cheese dip, mustard/mayo, various salad dressings, honey (not honey flavored dip, just pure honey,) and a few dips that require extensive use of the spice rack. Those last dips would probably need to be made beforehand and chill in the fridge for a few hours. There would also be a few empty small bowls if we wanted to mix a couple or three dips together.
Then we would sit on the couch together and talk... or maybe just sit for a while. If our relationship is not good enough for us to be comfortable with some silence between us we shouldn't be having this date yet. Phones and TV remotes would be locked in a car for the night. One of us would probably be leaning against the other most of the time, and we would talk when we had something to say, and if we had nothing to say we wouldn't say it.
MID-GRADE:
There's this restaurant I know of, not terribly expensive, pretty good food, and it is built on a bluff beside the Tennessee River. We could order a couple meals to go, but we would only be going as far as outside. There aren't any seats but I could bring a blanket. Maybe a towel if the lady wants to go for a dip, but I'm not much for water stuff. We could sit on top of the bluff where we could see the whole river or we could go down and sit on the shore itself. And as before, we would talk about stuff, or maybe not, but we would sit together a lot.
EXPENSIVE:
This would be like the budget date, but it would be in the Opryland Hotel and it would be catered. Opryland Hotel bills itself as the largest non-gambling hotel in the USA. The hotel rooms are in halls built around very large areas that are basically the outdoors, brought indoors, climate controlled. Here is a picture of the Delta area. Remember this is INDOORS.
We would get one or two rooms with balconies overlooking Delta. One if we were already married, two if we weren't yet. We would also get a couple of connected rooms for the catering staff to use as a staging area. The caterers would be from a catering company that has never heard of hot dogs, but knows how to make wonderful things out of pastry, cheese and mushrooms. We could plan a menu of little bites of things but I would rather ask them to just give us a lot of little samples of everything they have - hence the need for a couple of rooms for the staging area, as it would be impolite to impose on the hotel for facilities for the caterers.
After a long, leisurely meal one bite at a time, we would spend a few hours walking around the hotel and talking, or maybe not talking. Opryland Hotel takes a few hours to walk around and see, especially if you take your time and do it right. There are restaurants, pubs, Godiva chocolatier, gift shops, a steak house, even a nightclub though I never bothered sticking my head in there and getting my ears assaulted.
After ten pm though, that's when we would start walking and looking around for real. The stores are all closed, the crowds are mostly gone to their rooms and the place is... almost beautiful. The lighting is all recessed and set low to the ground. As it is all indoors, the temperature is always perfect and there are never any bugs. It's a wonderful place to stroll around, sit a while on a bench, just relax and enjoy the scenery.
And now you know why I'm single. I AM SO BOOOOOORING! But those really are my ideal dates. If the lady wanted something more exciting I would be up for it, but I'm quite happy to take a late night stroll in a beautiful place with a wonderful woman.
