The key is to strike a balance. Have them both go on the trip and they can wander around together while you sit in on a class, meet with the adcomm, etc. Explain to them that adcomms have said they frown upon involving parents in campus visits. Ask them to respect this. Have them go out on their own special date night while you go on bar review with 1Ls. I've never once had a client not get invited out with a group during an individual visit. In fact, the ones who do individual visits seem to end up more informed than the ASW visitors due to this.
Then, involve the parents heavily in the housing search (at this point it's okay to be seen with them if you look at on-campus housing). This is where they have superior knowledge and they will be willing to pay more for a "safe" neighborhood. Be certain they understand how grateful you are to have parents willing and able to put you in this privileged position. Have a great time on the trip, bonding and taking your relationship with them to a more adult level.
Sound like a win/win?
