Dinner date

Completely new to SW. I've done my homework, but I'm still wondering about a couple things:

I was looking to book an appointment, incall, but not sure if I should just make an appointment for x hours or instead go for a dinner date. The question is: Is going out on a dinner date mandatory? My plan was to bring my own groceries and have a little cooking sesh, either I do the cooking alone or we can do it together, both are fine by me. I'm not too keen into the idea of going out, not against it either, but restaurants aren't really my thing, I'm more into the having a walk in the park type of stuff, or doing some running on the track, gymnastics or what have you, but mainly I just want to have a chill evening not having to worry about stuff, just have some mutual casual fun. No dress code, no unnecessary schedules, just chill out.

Also, what is the schedule for a dinner date usually like? I don't want to feel like I am racing against the clock. Just wanna do the cooking, eat, chill out, talk about whatever: life, work, childhood, even the goddamn weather for all I care about 😂 have a shower alone or together, sauna, jacuzzi, massage both receiving and giving (mostly giving I guess, but god knows my muscles are in a dire need of some work done on them), listen to some music, hell maybe do some singing even, I've been doing some vocal practices recently, but never actually sung, especially in front of someone, but what the hell, what's the worst that could happen lmao. I don't really have a set plan outside of the cooking, just want to chill out without worrying about the time. I've seen many advertising 2h for 400 and dinner date for 500-600, so would that strictly mean the dinner date is 2.5h to 3h? Or is it more flexible where it can literally range from a couple hours to multiple hours depending on the situation?

Also, not sure if it matters to mention, but I am from a part of the world where SW is legal, so all good on that front 👍
