That sounds like a great idea!! I've booked a flight home more or less straight after the tour (I'm heading over a month before the tour starts!) but I'm more than happy to push that back depending on how my bank account/ me is feeling definitely am wanting to explore London!
Omg I've been reading up too! Slowly checking things off and I actually think I'm almost organised (which I also know I am definitely not !) But from everything I've read I know we are going to have an amazing time!
There isn't even one place I'm specifically looking forward to, it's literally everything!!
