Those Hilton Odds are bogus. Viewfrom vegas.com updates them weekly.

Horseplayer Daily also updates them every couple of weeks. I have never cashed. But I did have $50 on The Cliffs Edge at 150-1 made the bet in late November that year. Also had Action This Day a couple of years back at 100-1, he made the the race.
This year I have made 3 future bets. And will probably bet 2 more in early January once I see them on the workout tab.
