Hotel blocks and shuttle Vent

So I have a lot of family coming out of state from New York to New Jersey maybe an hour or more drive. So I blocked out rooms at the hotel were getting married in and at a cheaper hotel that's pretty close. I felt bad that the prices are kinda high for the hotel the wedding will be held at so I also got a shuttle for that family so they wouldn't have to worry about getting an uber or taxi if they decide to drink. I called both hotels to see how many rooms are booked and they told me only 1 room total for both hotels. I was so confused! So my mom reached out to someone and turns out the family from New York is getting a Party Bus!!! From New York to New Jersey! Omg. I think they're having an after party at one of their houses after... which whatever.... I'm most upset I rented a shuttle for no reason now! Uhg me and my mom are trying to figure out what to do now. But I dont want to look like an idiot to have a shuttle with NOBODY getting on it. Sorry I just needed to vent!!
