My wife and I, who have been Las Vegas at least 12 times, are going back in April, primarily for the Def Leppard concert at the Hard Rock. When we mentioned this to our friends, who have also been to Vegas many times, they said that sounded like fun and they wanted to join us. We are going from Sunday, 4/7/13, until Friday, 4/12/13, and the concert is Wednesday, 4/10/13. My wife and I went over to their house the other day and helped them line up the flight and hotel. (I was glad that they did not reserve a room at our hotel, but they are right next door). While I like both of them very much, I don't want to spend every waking moment with them. At home we see them at most once every 2 weeks, usually it is once a month or even once every 2 months. My vision of this trip is that both couples will occassionally do their own thing, but that we will talk or text during the day and see if the other couple wants to meet somewhere. My wife and I would not be offended if they did not want to do what we wanted, and we would be happy to meet them later or even the next day if they had something planned that didn't interest us. Except for the concert, we don't have anything else planned, but I expect we will meet for dinner once or twice and share a few beverages occassionally. My son came over for dinner tonight and I told him about the upcoming trip and how I expected the two couples to not be joined at the hip. He looked at me like I was an idiot and said that if the four of us are going together, then it is expected that we will be doing most things together, if not everything. I think he is wrong, but he insisted that the other couple is probably under the assumption that they are going with us and that the 4 of us will be spending most of the time together. I would agree with that if we were going with Vegas rookies, but this couple has been there plenty of times and knows their way around, and they know what they like and do not like. Now, I will have the talk with them before we leave about how it is okay for us to have our own interests and do what each couple wants. For example, if my wife and I want to spend the afternoon at the pool and they want to go to Hoover Dam, I don't see anything wrong with telling them to have fun and asking them to let us know when they get back into town and maybe we can meet for dinner or drinks. Just as a general rule of thumb, do you think I am being rude by assuming that we will not have to spent 18 hours a day together? Is my son right? If you travel with another couple are you obligated to spend most of your time with them? If I am wrong, this could be a long trip. I like them for 3 or 4 hours every few weeks or even once a month. 18 hours a day for 4 full days is a bit much. Whattya think? Am I being a butthead?
