Input: Diving right into it

I and a group of my friends (6 people total) have gone on summer Vacation together a couple of times. We are a very tight Friend group as we have known each other for 15 years since we were around 5 (this will be important later).

Important Background: the main organizer of our previous trips suggested a trip to East Asia this year. Nonetheless, due to the fact that that only one other person wanted to join him, the idea fell through and defeatedly he said that someone else should plan another vacation. I decided to plan the next vacation. The rest of the guys agreed with me and we booked an Apartment for 6 people with an additional ability for someone to sleep on the couch (again important later). 

This brings me to yesterday when I get a text in the group chat from the original Organizer of all the previous trips that he's bringing two additional people on the trip with us and that it is final. Because he's the one whose account we paid from and bears responsibility and thus it's his choice. He then followed up by saying that one of the friends is our old time friend (someone I had no problem with) and the other is his uni pal, who we have never met and doesn't even speak our native language. This didn't sit well with me and A. because I didn't want 8 people in a six bedroom apartment and B. I didn't want some random guy who I never met on holiday with me. I then attempted to call the main organizer who didn't pick up his phone and had his roommate text me that he's busy and can't deal with this situation. Then this morning, I finally got in touch with the trip Organizer who said that his decision is final and that I get no say in this and that since the payments are in his name. This prompted me to send an angry text to him saying that we had a verbal contract and that he should remove the stranger or I'm not going to go on the trip and that I want my money back (3 people in the group disagreed and 1 agreed with me). He ignored my text saying I have to deal with it, so I threatened to write an email to the AIRBNB host saying that there will be too many people and that his apartment will be a mess if he allows it. Then I texted the stranger (found on FB) and said hes welcome to come on holiday with us but he cannot gonna live with us and will have to find other accommodation with the Organizer elsewhere while we will stay as a core group in the main apartment.

This evening I got a text saying I won (sure don't feel that way) and that it's down to the original 6 of us as well as that I am a toxic person.

TL;DR My friend invited a stranger on holiday with us, I threatened to ruin said holiday if he isn't removed
