After re-reading I like what someone else posted. Show up early and shrug when they show up late. "Oops" lol.
I just wanna know the reason you have to wait for them. Do they want you to park a specific place or way? Maybe offer to pick one of them up on the way up, so you can park in the right spot and then have your wife drop them back off after, since they are only 30 min away?
We have friends that have a big yard, and sometimes we "camp" in it. They typically say just come after a specific time and set up, whether home or not.
And I also want to say that while this is "important to the wife" to go up there, its also "important to the husband" to have a certain amount of time to spend up there. Its a two way street, right?
To clarify what I said earlier, I did not say that the OP should tell her no, (though some other posters may have), but rather to tell her to go ahead, just she has to do it on her own. This has a dual effect, one which is negative (asking her to do something she has never done by herself in an effort to get her not to go), and a positive one (having her learn by having to do it on her own, so she can do things like this).
