My aunt and uncle just offered to throw us an engagement party, and asked us for a list of people we want to invite and suggested we invite some friends from school and work. We're having a small wedding so only our closest friends will be invited, but it would be fun to celebrate with everybody! Since this isn't formally a "gift-giving" type of party, is it okay to invite our classmates and coworkers even if we don't intend on inviting them to the wedding? My aunt and uncle have a very large space and love to host large parties- they have summer bbqs with 50+ people every year- so I'm not worried about having too long a list!
