I run three trips a years and have done so for a few years now. Filling spaces was hard going for the first couple as I was not well known. Usually my trips sell out in days if not hours, these are to a depth of 35m max.
I have a Plymouth weekend in June where one day is 44m, and I still have space (1), day two can be filled easily enough. Day one we are diving the Totnes catle which is to deep for many regulars and not deep enough for most trimix divers, but Dave and I want to do this particular wreck.
I offer trips at a price and take the risk. If I have an empty space some generous souls will chip in a few extra quid, there are some generous and like minded peole on YD.
I never arrange accommodation. I provide useful information and my plans, but som epeole camp, others bunk house others 5 star, all for £25 max.
Always take a substantial deposit to confirm the booking, even from friends.
I have now stopped organising trips that will meet other peoples desires, the wrecks we do are what I want. Seems only fair as it is me arranging the boat, checking tides, gas supplies etc
Right I am off to Brighton now
