Since this task is fiction and I have no idea where my school
would be located, I suggested leaving from Brussels, but hiring a bus to
bring us there is not a big problem.
On Monday the 8th of May we leave in Brussels around 8.52 am to go to London St Pancras. We arrive there one hour later, around 9.57.
The hotel is located close to the St Pancras international and it only takes 13 minutes for us to get there.
We put away our stuff, grab only the necessary and after freshening up, we're ready to go! The students get the chance everyday to go purchase something to eat, so before we get to the Buckingham Palace, they can go around the neighbourhood and explore really quickly.
