I'll give you some background on Type I and Type II errors and let you take it from there.
Type I errors result when you reject the null and it's true. Type II errors result when you accept the null and it's false. You can reduce Type I errors by setting the alpha at a lower level, for example, from .05 to .01. However, when you do that, you increase the probability of making a Type II error. You would have to determine if the hotel would be more concerned about Type I or Type II errors.
