when E-Mail is send to receiver and transmitter I want to …
1. … send also the name of the apartement for which is the booking (because I have more than one apartment/site with booking calender
2. … send not only the price of all extras together, but also a list with the single name and price of each choosen extra (because it is important to know which are the chosen extras)
If only the entire sum of the selected extras is send in the email that makes no sense. The e-mail must send what extras the guest has chosen. Does he want towels and sheets? Or just towels? For Example. What would you charge for this feature?
