I tend to agree with others posting, usually a DW will cut down the guest list. For me, I never wanted a large wedding. I am only inviting my two best friends and our immediate family.
I felt guilty about it for a minute until I was reminded by my sister who just got married (large local wedding) that no matter what, whether the wedding is here or away, big or small, I will unintentionally hurt someone's feelings. Its just apart of getting married.
In an effort to help, see what deals you can get for some of your guests whether it be at the hotel/resort, airline tickets, etc. We are paying for one of my friend's plane tickets who we want there and cannot afford the plane ticket and the rest of travel costs. Flying to Europe is really costly. We are also going to pay for a group excursion during the wedding week so we can spend extra time with our guests doing something local. I know if we pay for the day excursion, it will cut down on some stress for our guests. I hope this helps, good luck.
