I believe it would be a good feature to add categories like "Parking (free, lot, metered, etc.)", "Payment Types Accepted (Visa, MC, Cash, Bitcoin", etc.
It would help people plan their trips better.
Also: closest ATM, in case of "no cards, only cash - record stores" :D
And nearest bar so you can drink away your guilt from going over your budget?
Good idea. There are so many record shops that only accept cash (in Germany). Very time consuming - if you don't know it, you are rather looking for banks than record stores. :)
A "Cash Only" marker would be especially helpful
Could this be put in a notes or comment field?
For now, most certainly. I'll start adding it to the notes.
