Surprise trip to kaliningrad

We are a young couple (21) and (20) who had to leave university due to financial struggles. We managed to find jobs and living from paycheck to paycheck and recently moved to czech republic.

My girlfriends birthday is coming soon ( April) so me and her parents wanted to make her a surprise trip to kaliningrad, Russia which she always wanted to visit and her parents will be there too( they live near to china) so she havent seen them for around a year now.

The problem is that i am running short of money for the trip as flights are too expensive and accomodation, etc... as i said we live from paycheck to paycheck. So i would really appreciate any support to make this trip come true as i know she would be the happiest person ever.
