IMO physical bookings will be legal again from May 17th, when two households can mix indoors. Masseurs, hairdressers, nail technicians can all mask up and we're not shagging/kissing them...
Re. vaccines, I don't really see it as a marketing point, nor would I believe punters who used their vaccination status as a bargaining chip to obtain a booking. Moreover, by the autumn it will hopefully make little difference as enough people will have been immunised for the country as a whole to achieve at least some level of herd immunity, so the odd individual who hasn't been vaccinated shouldn't be a, or at, risk.
