Hi eyesickle1,
If you are age 31, as your pprune profile says, then unfortunately you cannot apply due to being over the age of 25.
If not, or for anyone else wondering the same, then yes Eurocontrol will reimburse your travel expenses for each visit. They will provide the hotel accomodation, but you have to book and pay for your own travel, then submit copies of the tickets etc when you attend, and it will be paid into your bank account after each visit. So although you don't end up out of pocket for travel in the end, you do have to pay to begin with.
