oh man that's the worst. Anything involving multiple people.
We are going through it. A cousin has a medical issue that will deteriorate and she wanted all the cousins to get together. A person took charge and found a place in Georgia. A tad expensive but I'm ok with it since it's for our cousin and I won't miss that money in 3 years. Booked our flight, got our car.... now the person in charge is like "Well they aren't giving us the discount and I know some people thought it was expensive.... what if we all met in December instead in Michigan?" Then you have a bunch of other cousins saying "yeah, that's good" and others saying "We can't guarantee our availability", blah blah blah. Just a cluster.
it's my wife's cousin so it's all the females handling it. I told my wife to tell them "We will be flying into Jacksonville that weekend to go somewere... if anybody wants to join us they are welcome to"
