We are going to London!

Hi, guys. Next March, my class and I are going to travel to London.
First of all, I'm very excited because I have never been in (or to) another country and the most important thing... I have never travelled by plane! Due to this, I'm very nervous, because it's a new experience, yes, I know, but... What if something doesn't work well? If I get lost in London? What am I supposed to do? Calling someone? Asking someone to help?
On the other hand, I really want go to London and seeing Harrods, the Big Ben, the London Eye...
My dream is to go to London at Christmas, I think the city would be very beautiful in that season.
Well... I think that's enough for today.
Bye bye and see you soon!

I'm excited for you. I'm sure you'll have a great time!
