At least hscottm can see it. I have opened a second window and I can still see the rate now. The problem may be:

1) You must be a registered member of travelocity

2) Search hotel, using the 'by airport' option (2nd option), type in MEX (airport code of Mexico)

3) Preference set at: "All Hilton brands"

4) Number of people: 2 Number of room: 1

5) Click "Search Now" at the bottom of search page.

6) There should be only one option b/c there is only one Hilton property in Mexico City and click "select" when you see the hotel. The price range given on the right hand side of the screen is inaccurate. Once you click "select" you should see 4 types of rooms: 2 choices are 2 doubles for $130 per night while 2 other choices are at $0 per night with one King size bed and another, bed size unspecified. The type of rate is: Corporate Rate except one of the Doubles at $130 is Best Available Rate.

Hope this helps.
