My[29/M] wife[29/F] feels unconformable with me going to Vegas with a group of guys I haven't met before

Backstory: My now wife and I got together in 2013. During that time, I introduced her to one of my good friend (Female), who after a few months, introduced my wife to her other group of female friends. My wife, along with the big group of friends, would plan "girls night out" trip, which includes going to Vegas (or other destinations) once a year, and dinners a couple times a year. The first time my wife went with these girls to Vegas, there was only about 6 girls, only one of whom she hadn't met. Now the group has slowly expanded every year to 12 girls. These yearly trips have now been going on since 2014, and my wife has attended most of them.

Fast forward to now, we are both 29 and married. One of her best guy friends has invited me on a trip to Vegas, with a group of his friends who I've never met before. He has a history of not being faithful to his partners, but other than that he's a wonderful person. I've never really been invited to group events, so I thought I can take this opportunity to make some new friends and go out of my comfort zone. Unfortunately, my wife is uncomfortable with this because she thinks we are too old to go to Vegas with people I'm mostly not familiar with. I don't see it that way. My reasoning is that even though I was uncomfortable with the things she was doing (clubbing, strip clubs, etc), I bit my tongue because I trusted her and didn't want to restrict her from having fun.

Her argument is that she was young at 23 when she started going to Vegas and she already knew the girls (4 out of 5) before going. Now she goes with the same group of girls (established in 2015, when she was 25). Of the 12 girls, 4 are married, 3 are married with kids, 5 are in a long term relationship. She says that our situation is not the same, because we are now married and our focus should not be going to Vegas to party with random guys that we have never met, especially with a group of guys (including the unfaithful one) that I do not know, and she does not trust.

Now, I never had a problem with her going out with the group of girls. I wasn't the most outgoing person when I was younger, so attending group events wasn't something I did. Now that I'm older and a bit more social, I find it easier to get out of my comfort zone and meet new people (maybe even make some new friends along the way). Keep in mind that I would never jeopardize my relationship with my wife over two nights in Vegas. I have and always will be faithful, and use my best judgement in any circumstances.

Reddit, what do you make of this situation? Does my wife have a point for me not to go on this trip? Or is it within reason for me to go?

​

TL;DR - Wife goes on yearly Vegas trips with her friends starting at 23, and got upset when I wanted to go on a guys trip with guys I don't really know at 29 because she believes it's not the same situation.
