As a general response to uncertainty, half-speed can have advantages. Specifically:
This signals your uncertainty to others—someone more familiar with the area may offer to help.
When (and if) help is offered, you are less likely to have gone too far the wrong way.
Now, neither of these were applicable in your specific hotel case—had there been anyone to ask, you could have stopped and asked, and going slowly in a car doesn’t really help you. So it makes a lot of sense to ignore the default strategy in that case—and, in fact, in several other cases as well (it’s a common heuristic, but it really doesn’t apply in a lot of situations)
