@Mike-And-Jane0 In fact, while they may be impersonal, hotel's do have concierge desks to help guests plan their trip - and they pay the additional hotel fee for the extra attention.
A guest would not expect to be able to contact a concierge with multiple questions prior to their arrival, they would have that conversation at the desk after they have arrived.
If guests want a concierge service, they should book a hotel, not vice-versa.
I have an extensive guide book on my listing, brochures of local sight to see in the studio and share my knowledge of my city with guests if they ask. It should not be necessary for me to plan their sightseeing and I would hesitate to do so anyway in the fear of the almighty 'review'. If they don't like what you have organised who knows how a guest would score....
Having said that, if I could add a sightseeing itinerary by asking questions of the guest regarding their interests, reason for visiting etc, as an additional service for my hosting in the same vein as an 'experience' I would jump at the chance - sadly I tried and it is not possible.
