It's like travel to any touristy spot. If you want to buy merch, drinks, and splurge on things than it'll ramp up quickly.

But if you're sticking to the basics like breakfast/lunch/dinner + snacks and not buying anything other than essentials than $100 a day should be fine (or $15-$20 per meal).

Please Help.
Thanks !
I didn't find the right solution from the internet.
