Here is the update I got from Quinn McGinnis who is part of the Ireland team:
The Ireland Team has arrived safe and sound in Belfast. We were detained, however, for an hour and a half, at Belfast International, because they thought we might be working for money (and in that case we would need a work permit). Graeme and Christine met us at the airport and are basically managing our trip. We are at Derryvolgie Hall in Belfast where we are staying for a few days for orientation. After that we will go to our first camp at Faughanvale. We're all very tired, but doing fine. Thank you for your support, prayers..
