Snowflake and DV have no interdependency whatsoever. Snowflake is just a database. Whether you use DV to model the data inside of it or dimensional modelling or "big wide tables" is completely up to you, there's nothing about it that requires or benefits DV in particular.
In this case, the trainride IS the vacation. You don't take the Trans-Siberian primarily to get from Moscow to Vladivostok / Beijing, but to check out everything else along the way.
I think your post illustrates well why both languages are important to have. I also work in the Business Intelligence - space, but my job is usually more focussed on setting up data pipelines and developing a small specialized web app here and there. So if I'm already doing that, and I do analysis on top of that, of course I'm going to pick Python, because I can stay in the same ecosystem and I already have a better feeling for how things are going to work. But this wouldn't make sense at all for someone who generally works more on strategy and decision making and wants to dig a little deeper from time to time.
Although when people ask me for a recommendation on what to learn, and they're actually interested in programming and building things themselves, I always recommend them to at least give Python a shot and see if they like it, as it then also gives them the possibility to do a lot of other things with the language.
This doesn't happen. People are just applying stereotypes to every possible context and situation. Germans are perfectly capable of coming to a BBQ later than the scheduled start time, although it's true that unless it's impossible for them to make their schedule fit with yours, if you tell them 5, then 5 it is.
Because of this, I would say it's even more important to schedule things sufficiently ahead of time. Making up plans only 2 or 3 days in advance, when weekend plans are mostly settled and they can't properly schedule around your event, will just stress people out.
Most people don't drive the kind of car that can comfortably average 180 km/h over such a long trip. Even if I did, I probably wouldn't always do it because of the fuel cost. Driving fast can easily double the cost of your trip compared to driving efficiently. At which point I'd rather just spend the money on a train ticket (given the choice). Driving that fast is hella stressful
There are buses that travel at night, but they're not comfy. i.e. they are not designed to be comfortable night-mode travel. In general, distances are too small to consider overnight trips. Since there aren't many good roads in Myanmar, trips take forever, which makes overnight travel sensible.
