Janet, old is a relative term. Seems to me, you're right in the middle of the pack. My husband and I have been to 2 Gatecons, both in Vancouver. We arrive a couple days early, and get in a bit of fishing and touristy things. It's a pretty long flight from UK, so I suggest you try to see some of the beauty of Vancouver in addition to all the offerings of the convention. Don't worry about not knowing anyone. Everyone attending is friendly, and also interested in getting acquainted. The organizers are top notch, and, when they have time to come up for air, are some of the warmest and friendliest folks you could ever hope to meet. Looking forward to a wonderful time with wonderful new friends.
