I had the problem when I was in high school an if they are your friends they will bite there tongue and have a good time with you whether they get along or not that is what real friends do

is this chinatown in london? :)

Go by yourself then e-e

Or say--- "if you truly are my friend, you'd respect my decision when i say i want to go with the both of you"
DONE
GO WITH THE TWO OF THEM
AND HAVE LOADS OF FUNN
AMEN

This happened to me many times before. Tell them both "I invited you two because you're my best friends. I could've easily invited anybody else. But no. I chose you two; an I'm really looking forward for this day with you two. I love you both and have an amazing relationship with you two, I don't want your problems getting in the middle of us." Then tell B, "I've been spending more time with A because were both still in college.. You're working.. You and we can't do anything about that. So get used to me and A hanging out together. It doesn't mean that I like her more than you, co you're both my favourite.. But we always see each other." Tell A "you know how much I'm looking forward to this, please get along with B.. If you treasure our friendship."

It works for me everytime, and they even become bestt pals XD but of course, if they DONT listen to you, go with friends that respect your wishes and who actually get along together.

Go with each of them in different day? Or bring another friend (C)you walk with C and let A and B walk together, hope it can fix their issue but make sure you always near them so they didnt feel ignored by you ^^.

i would choose my best friend, who you feel more about her(trust, ...etc) or who is more interested more about it and bring her with you so you could have fun i guess

I think that if they cant be friendly around each other for your sake thats not exactly fair to you and isnt very friend like but like the others said you could:
1) lock them in a room so they can work through their issues
2) go alone
3) try going different days with each
4)try to go with both and hope it doesnt end in complete chaos
Or
5) go with more friends
Sorry this probably doesnt help at all -.-'

can you invite more friends to go with you? so it won't be awkward with only the three of you.
otherwise, i go alone if i were you. i would definitely rather go by myself.
*sorry i know i'm not much of a help here* ㅋㅋㅋ

get more friends to go

Lock them up together and let them talk about their issues?

go on saturday with friend a and again on sunday with friend b?
