I understand you're Russian and your country's norms are different from ours but bear with me. It's good to see that you're on a date with her, well done but what you have planned tomorrow really seems a drain on your money.
I study natural pick-up, I make structures for myself, rules for myself, things I should and shouldn't do on the pick up.
One of my rules is not to make a date expensive on myself or the girl because it can make her think the following: 1. I'm a push over and I'm being needy because I'm paying the whole date. Or #2 if it is expensive on her then she is going to home thinking "wow I'm nearly skint" this will put her off going on another date with you.
Don't get me wrong, the expensive dates can come just wait a little while, do something a little more inexpensive such as lazer quests they can be real fun and they don't cost much.
Good luck man
