Why are people getting downvoted for defending them for not attending? Most fundraisers aren't actual reimbursements, they're just a percentage of the reimbursement, and if you come in 1st you MIGHT break even, considering the astronomical cost of everything else there.
You have to pay for the flight there (at this point in time, it's probably at least $1000 from the closest places in NA, hundreds more as you go west), the hotel, the transportation, the food, and lastly, the drinks, who almost everyone will partake in, as you don't just go halfway across the world to not socialize and have fun. If you have all the money settled, and you actually want to attend, you have to take off of work that Monday and likely Thursday/Friday, maybe even Wednesday if you decide you don't want to spend only 3 days at a tournament where you'll be playing for almost 2 entire days. In reality, for those who work regular schedules, you're losing even more money than simply the amount of the flights, travel, and LAN.
I really enjoyed going the first couple of times (the second time only because I met everyone I hadn't met the first time), but any amount more and it becomes kind of tiring. You dread the travel, you dread playing day 1 from like 9 am to midnight the next day on jetlag and minimal sleep, you dread the loss of money. It's not like it's some kind of fucking conspiracy that no one wants to go, as if you're all better people who would die for a chance to go to LAN and you're disappointed that everyone on froyo is missing this deal of a lifetime. Yeah, no shit, it would be your first time there, you're thinking entirely hypothetically, and you have no idea what the process actually entails. Once you've experienced everything, it can become not only overwhelming, but you can easily think of more reasons to not attend than to attend. And as banny says, if one person doesn't want to go, it becomes a domino effect. One person not wanting to go makes the next person, who thinks his presence invaluable, uninterested in attending. If you're going to spend money out of pocket to miss days of work and attend a LAN in Europe, you're going to want to do it correctly, with a real roster.
