"At a hotel" or "in a hotel"

What is the difference between at a hotel and in a hotel? The NYTimes seems to be using both of them. I looked up the ngram on google and it seems in a hotel is used more often than at a hotel, which is kind of surprising to me.

Solution 1:

In a comment responding to the original post, Eduardo advises the poster to add a verb in front of the phrases "at a hotel" and "in a hotel" to obtain a more precise idea of which phrase is more common. I ran Ngram-based Google Books searches for three pairs of verbs + the phrase "in/at a hotel" over the period 1850–2005 First, "met at a hotel" (blue line) vs. "met in a hotel" (red line):

Second, "stayed at a hotel" (blue line) vs. "stayed in a hotel" (red line):

Third, "stopped at a hotel" (blue line) vs. "stopped in a hotel" (red line):

Clearly, the choice of verb has a considerable effect on the choice of preposition, assuming that all other factors remain effectively equal. But that's a major and probably unjustified assumption.

One major further complication involves the presence or absence of a noun following "hotel" in the phrase. In all three verb phrases that I tested, the "in" phrase was likelier than the "at" phrase to draw a following noun.

For instance, in the Google Books/Ngram results for "met at a hotel" versus "met in a hotel," in the first ten results for the 1987-1998 time period, "met in a hotel" was followed by a noun—suite, elevator, bar, room (three times), or restaurant—seven times. In contrast, "met at a hotel" for the 1938-1998 had only one following noun (suite) in the first ten results, although subsequent results offered such additions as garden brunch, swimming pool, and resort.

The phrases "stayed at a hotel" and "stayed in a hotel" were far less often followed by a noun in the Google Books results than "met at a hotel" and "met in a hotel" were. In fact, I didn't see any examples of a following noun involving "stayed at a hotel"; in contrast, "stayed in a hotel" did occasionally show up as part of "stayed in a hotel room." The Google Books search couldn't find any examples of "met at a hotel room," "met at a hotel lobby" "met at a hotel bar," or "stayed at a hotel room." It found "in" versions of all of those phrases.

These results lead me to hypothesize that, overall and in everyday usage, the phrase "in a hotel" lends itself to further narrowing by a following noun (especially room) to a significantly greater extent than the phrase "at a hotel" does—and that this phenomenon muddies the waters in any effort to determine by means of a simple test which simple phrase ending in the noun hotel ("at a hotel" or "in a hotel") is more common.

Solution 2:

I think in a hotel is more specific. It means being inside the hotel. When you use at the hotel it can be both inside our outside.
