Can anybody who's not in the U.S. access this website and see if there's current and updated odds for the last four standing? http://sports.williamhill.com/bet/en-gb

I know it is a little late to help you for this event but if you use the site above it blocks your location from being "seen" and will let you look at williamhill.com for future events since your location is anonymous/unknown. There are other ways to view sites that have your area/location blocked but this one is by far the easiest and cheapest (free) in this particular case.
Not sure if you could place bets through this or not (they may or may not accept bets from individuals whose location is anonymous, I haven't tried) but you can for sure look around the site and see the odds etc, and there may be other sites that block anonymous traffic altogether but williamhill.com doesn't (at least for perusing the site anyway).
