I could have sworn that I posted in this thread yesterday but... uh I guess not. Anyway, your best bet is to check out this thread:

Then go to the store that has the most Wii's coming in your area about 3 hours before opening. I think your 2 hour limit is a bit low and will result in you leaving with your money and no Wii. Also, don't be afraid to call stores to see what their gameplan is for launch day. (Midnight release, early open, how many consoles, etc etc.)
