Until recently, thought it was also named after Pythagoras, with the snake being a double meaning.

My first thought was also that it’s a Pi bottleneck. I have a 4b, and I don’t think I would really trust it to handle some of the higher-quality streaming. Maybe just barely.

Where do I fit if I use all three?

That’s dumb. I used to work in hotels. We hated online bookings because of how terrible those sites handle expectations. A tip for the future is: If you find yourself wanting to take that latter option, odds are it’s the same as booking directly, price-wise. If you book directly, you’re more guaranteed and only have to deal with their own policy. Usually it’s no fee if cancelled the day before arrival. If cancelled same day, a one-night fee applies for holding the room. If you cancelled the day before, could’ve saved.
