The city tour getting cancelled is such a travel mood decent Wi‑Fi, nowhere to go, and suddenly the afternoon lasts forever. I had something similar on a work trip when everyone else went sightseeing, so a few coworkers and I played cards online before dinner. If you’re considering it, son33 might be worth checking out, but I’d still read the terms first, confirm it’s legal where you are, set a firm deposit/time limit, and treat it as entertainment rather than a way to win money. Better than staring at the hotel wall, at least.
