Meeting them at a location??? .... so we're not entertaining the suggestion of Meeting the client on the phone"

"
I'm finding that whatever the clients used to feel they gained from a face-to-face meeting is being satisfied by the information exhange which happens on my initial (post-contract) paperwork, telephone calls, or emails - even though I offer a face-to-face meeting at their preference, I don't have any reason to insist on one - eg: Fee justification.
My "Additional Information" paperwork covers such things as "Best mans name", "Bridemaids names", "honeymoon destination", "Will both sets of parents be there?, what are their names?, "Are there any recent family bereavements, divorces/re-marriages, key abscentees etc, which I should be aware of -" etc.
If/when asked, I usually cover the last point above, in more detail. What I'm keen to avoid is of course a mic announcement of say "Please may we have Diane and Steves parents up to the dancefloor" when perhaps Dianes Father died 2 years ago.
Some such annoucement gaffs are just un-avoidable. I went to a disco at a friends wedding about 3 years ago where the DJ ended the nights entertainment with "And lets wish Sue & Steve every happiness in the future, and lots of kids very soon...". Half the dancefloor turned around and advised that the kids bit was somewhat unlikely as Steve had had "the op" several years previously - some also added however, that the local milkman hadn't had the op...
When a face-to-face meeting is still requested, I'll normally suggest the venue that they've booked. As its primarily hotels that I perform at now, it means that there will be comfy seating, refreshments, and an opportunity to view the dancefloor/disco area etc, with the added bonus of being able to bring the venues conference/banqueting manager in "live" on any joint decisions, if needs be.
