Thats my point, I don't think for one nanosecond that there will be any danger of these two being harmed by even a low flying sparrow because every inch of the 8 day route will have been security swept prior to and during the event by an enormous amount of highly trained ,skilled and expensive personel.
I would like to know the true cost to the taxpayer for this little jolly especially when we are being subjected to global financial meltdown .
I hope they have their money in the Channel Islands branch of an Icelandic bank. 
I sincerely hope you are right Olympia, but even American presidents surrounded by more security staff than we will ever know about still get assassinated, and even whole army divisions are struggling to contain both the Taliban and Al Quada.

The princes really shouldn't be putting themselves and others around them at such risk at, as you state, enormous..........public expense.

No-one asked me if I wanted to donate to the chosen charities, but I, and all British, taxpayers will be indirectly with the costs involved at a time when the military funding is under increasing threat. I hope they do raise massive amounts for charity, but surely there was a better way to do it!

OK, rant over...........
