Keep BTP premises parallel with the North Ramp, but move West and resize allowing for the creation of a ScotRail first class lounge on the current site of BTP. Virgin First Class Lounge kept where it is, create a through link from ticket offices direct to lounge and Platforms 3 thru 7.
ScotRail first class lounge will have direct access to the gait lined Platforms 16-22, in theory all ScotRail first class equipped trains would be departing Platform 14-20, going by above plans.
Creating a familiar space for frequent passengers and an easy to use space for everyone.
Taxis...
On Waverley Bridge there's currently 10 bus stops/bays, 2 Airlink, 1 Airlink reserve and 7 Tours. Create 1 Stop for each Tour, City Sightseeing, Edinburgh Tour, Majestic Tour, 3 Bridges tour and the Ghost Tour, which can be shared with other city tour operators. So that's 5 bays, with excess buses queuing on Market Street (West/Mound side). 2 bays for Airlink. Lothian already have a bridge manager for tours and Airlink.
In total 7 bus stops, creating 3 free stops. Those 3 stops should be turned into a Taxi Rank with enough space for 8 taxis - appoint a marshal. Waiting taxis can do so in a waiting area in New Street carpark, which can also act as a Taxi Rank - appoint a marshal for the rank.
Create 2 coach stops on Market Street East for coach parties and rail replacement services. Appoint a manager to manage the Coach Area when necessary. Extra coaches can wait on Market Street West or Calton Road.
Lothian Bridge manager is in charge of making sure a maximum of 7 buses are on the bridge at once. When a bus leaves, then another can be request another from the Market Street West Manager.
Taxi Bridge manager in charge of making sure only 8 taxis are on the bridge at one moment when one leaves, others can be requested from the New Street Taxi rank. Drop offs can be done so on Calton Road or in a drop off only point on Market Street East.
The overall bridge manager is in charge of everything and is able to hand out fines to excess buses, coaches or taxis on the bridge or Market Street East.
Create a public drop off point on Calton Road.
