Amend category, discount + add extra

• Anne calls, two other friends are coming, so she would need to upgrade one of the rooms, to have 3 people in it, if possible.
• The friend’s name is Emily Kane and Ari Lane and they would like to have breakfast.
• They will also leave super early on Monday, and Anne asks for a discount?
• Change the price for the last day of Anne’s reservation to be 10 EUR cheaper.
