If you have a really sore stiff neck, high fever, chills and the symptoms came on rapidly, like you speak of, you should get checked for meningitis. If you were staying in close quarters at the hotel in Mexico is is very easy to have an outbreak of meningitis. I would definitely go to the doctor and get checked out. Better to err on the side of caution with those symptoms because many of the symptoms of meningitis mimic those of the cold or flu.
