Hosting 40 man tourney....

[SoloAJ]

Last year we had a 27 man tournament. Starting chips 1000. Blinds half hour long. Tourney took 7 hours. No one minded that, it took a long time and ate up everyones night, gave thme a good time. However, I have run into a problem.

This year we expect about 40 people. Some of the guys are wanting to have unlimited rebuys. So we are thinking of doing unlimited rebuys for first hour or hour and a half. The starting chips will be 1000, and you can rebuy 1000 chips if you go bust and only if you go bust.

Blinds tentatively are:
5-10
10-20
15-30
20-40
25-50
50-100
75-150
100-200
150-300
200-400
300-600
400-800
500-1000
600-1200
and so on....

Does anyone think that with unlimited rebuys this tourney could possibly take....forever? Blinds we are thinking of upping every 25 minutes instead of 30. I dont mind if the tournament takes 7 hours, but if it goes way beyond that, then it becomes a big problem. Any advice for the blinds or something I can do to make sure it doesn't last into the early morning?

If you need anymore info let me know and I'll try to post it.
