Do hotels omit the 13th floor?

Question

Triskaidekaphobia is the fear of the number 13.
But do (western) hotels cater to this phobia by skipping/omitting the 13th floor?

This USA Today article (2007) quotes J.W. Marriott Jr., chairman of Marriott International:

"It was one of the first things I learned: Don't go to 13. "

also from the article:

Hotels without a designated 13th floor are so much the norm that fire departments generally assume it to be the case.

"Changing now would be the issue, and cause confusion," says Alejandra Castro-Nuñez, spokeswoman for Miami-Dade's fire rescue and homeland security department.

Dilip Rangnekar, spokesman of the Otis Elevator Company (2002):

"Based on records of buildings with Otis brand elevators, as many as 85% of the high rises in the world don't have a 13th floor." (source)

My question:
Are there statistics on how many hotels omit the 13th floor?
Is it just a minority or actually a widespread phenomenon?

On a side note:
Apparently there are airlines (e.g. Air France, Lufthansa, Continental) that don't have a 13th row.

Answer 1

Not about hotels, but an analysis about all closed co-op and condo sales in Manhattan, in 2009.

Jonathan Miller

did an analysis by floor level of Manhattan co-ops and condos, which illustrated the market phenomenon of the missing 13th floor in Manhattan.

Older buildings are more likely to be missing the 13th floor than new ones.

...

13th floor – data suggests only 18.4% of buildings with a 13th floor actually call it that.

Real Deal Magazine:

Miller's analysis [...] found quantitative evidence that, yes, apartments on the 13th floor are statistically unusual (note that floor's small market share for 2009 sales). That superstition, it seems, dies hard.
