Hi OMM
Couple of points that I'd like to make:
1) DO NOT (and I can't stress this enough) DO NOT allow GW any say in ticket allocation. If that happens then I guarantee that the UK contingent will be disproportionately high. GW are the worst kind of partisan organisation I know.
2) I appreciate there is a kudos in holding the World Cup at GW's Headquarters, but to be frank it's a lot of hassle to reach for the rest of Europe. Amsterdam (or another central european captial with an excellent international airport), or London would have been better. The event will, ultimately, be judged a success or failure based on the coaches who attend and their experiences, not on whether the place was pretty or not. By all means the venue adds to the experience, but it does not define it. It's not like Warhammer where they need the special sculpted boards.
3) Consider the option of additional, on site, playing space for coaches (e.g. external marquee, portakabin, etc) to increase the number of players allowed). There will be a LOT of players who want to come, especially if this replaces the Eurobowl next year. This Eurobowl had 96 coaches and that was with a limit of only 8 per country. The GW hall has fire restriction limits.
4) Keep ticket prices reasonable. Not everyone can afford international flight plus travel from London/Manchester areas (where most cheap flights go to) to Nottingham.
5) Travel arrangements. Nottingham is, again, a bloomin' awful place to get to if you're travelling from abroad. The UK public transport system is slow and expensive, which is why most of us own cars. Provide foreign travellers with details of how to book trains (the trainline), cheap cars, national express coaches, etc.
6) The time allowed for games should be 2.25 hours minimum. A game can be played in 2, but it's a push. This is a once in 4 years event, so please don't spoil it by making people rush through games.
7) Use the community to provide the scoring system, not GW. Either Yavatol's "Score" system or the Eurobowl program (that has players enter results, not organisers). EVERY time GW do it their way they take 30 mins to enter between rounds and have numerous problems - regardless of whether it's BB, Warhammer or 40K. Next round for Score/Eurobowl is max 10 seconds after the previous round finishes.

DO NOT (and I can't stress this enough) DO NOT allow GW any say in ticket allocation. (just thought I'd make this clear

)
