How do you guys spend so much??? My friend recently came back from tokyo and he spent $25 per night on hotel! Fair enough it was the basics, but what the heck are you gonna do with a luxury hotel when you'll hardly be in it??
As for food, he spent about $15-$25 per day (on average) for breakfast, lunch and dinner while still having nice food! But of course, sometimes he went to exquisite restaurants, but he said they wern't that special because a nice meal in a standard restaurant is just as good!
I think people generally let themselves go when they're on holiday, but if you're careful you can have a great time whilst not spending so much. This way you will leave more money for souvenirs or technology or anime or whatever you want!
