Welcome Eli!
It's really funny cause it feels like you just described me, without the job bit
I am actually planning to go to London myself in the next couple of months. It's a bit annoying cause i can only book it 4 weeks prior, because of my work rota, and sometime it gets all booked out for the days that I want. I will manage it in the end!
But yeah, welcome again to Gryffindor! I hope you're gonna have as much fun as I'm having now! If you need any help, feel free to PM me! :P
