In short the rules can say no refund, but surely humanity could be considered as well.
Surely in the past there was people in any event that did not want to partake, and used sickness or death as a way out, being part of the lies conmen use in this world of ours, but if they (orginisers) had any sense of humanity they could have asked for prove ie letter from hospital, and refund but keep a admin fee.
Surely if the event is as great as the past participates say, then there must be a waiting list for more entries, and they would not have had to make any changes except names of new participants.
Yes a lot of work and effort goes into arranging these events, but a plan can always be made.
Maybe if some of the orginisers were on WD, then they would realise that most people here are honest, and will not back out of a deal unnessesary, or without properly excusing themselves.
You can buy a car for 500k and back out of the deal without it costing you money. Why not something like this.
And yes I have been "bitten" before with the same kind of issue (not motorcycle related) and it leaves a bitter taste in your mouth, and influance your feelings of trust towards others, which is why I try and stick to the Dawgs for advice, and support dogs where I can as I "trust" the people on the forum.
But that is just my 2c, and maybe I am missing something, but I back Minzi on this one.
