Help my son travel to Europe with his dance group

Hello -- my son is part of the VALLARTA AZTECA traditional dance group and have been invited to perform in Europe this coming summer. The group will be performing in several different countries: France, Poland, and Romania.

The group is paying for hotels, but we need to raise money for airfare and meals during the trip as it will cost a lot of money.

I hope that you can help me. It is possibly a once in a lifetime chance for seeing the world and will expose him to many new things and ideas.
