We would like to have the ability to configure a tag on Surcharges and Discounts that if added to a transaction would add those tags to the booking where they are used. For example we have a Surcharge for those that want to utilize the HotTub. When we add this surcharge to a booking and save it the booking would be updated with the appropriate charges and the tag on the booking would now include whatever tag was identified on the surcharge to be added. (in our example the booking would now have tag HotTub attached to it). What this allows us to then manage is communication via tags... if a transaction has the tag HotTub we can send instructions on how it is unlocked... If it doesn't we can send a message describing the service offered and the pricing and asking if they would like to add it... ie if it doesn't have the tag... send the message...
Guest addons is another issue but I will put it into a different feature request...
