At Mr Bridge I started a series of events three years ago which were more seminar focused. Four night events with the three middle days having two seminars each. It is fully aimed at improving your bridge and immersing yourself in the subject.
The 3 main days, have morning seminar and set hands and then afternoon seminar and set hands. In the evening you have three choices: play a few more set hands; play a duplicate; or just take it easy. I do not direct the evening duplicates on these events; leaving that up to my team. Of course all of the sessions are optional, with the emphasis as always on enjoying yourself, but also to improve your bridge.
