It can be as stressfree as you make it! You have to keep in mind that not all of your guests are going to come and be okay with that before you decide to have a large destination wedding. I have 50 people booked and counting - and there is really nothing to stress about ... it will be amazing anyway!
Congrats on the wedding, I cant offer you much help, but I can offer moral support! It will be a beautiful wedding no matter where you are! Dont sweat the small stuff
I usually tell people that they have a greater chance of getting caught in the violence in the neighbourhood that they are currently living in just to deflect a bit!
