I agree with you & yes this so called 60% rule is ludicrous, but as most Nile Cruises are for 7/8 days it would be difficult to quantify that.

Also as half the holiday was ruined, especially the latter half shouldn't that include the flight home, as we were still feeling ill then, especially my daughter. I was frightened of making too much of a fuss in case they wouldn't let her on the plane to travel home. Didn't fancy an extended stay in Luxor with my daughter possibly in hospital (its only a hypothetical question as I have already accepted Cosmos offer)?
