FI and I are giving anyone over 18 a +1 invite, regardless of relationship status. However, we are wondering what to do about single members of our WP. Do we give them a +1 as well? We are not trying to exclude single members of the WP, but are thinking more in terms of how the +1 would feel spending chunks of time alone because the BM or GM is either taking pictures during cocktail hour, going around with the B&G to tables to socialize and thank guests for coming, etc. It may also be uncomfortable for the +1 if they don't know anyone at the wedding and have no one to hang with while their date is off with the rest of the wedding party. Thoughts?
