In terms of what people liked about WYD, let's just say that the food was not at the top of the list. In fact a quiz running on Xt3 (with around 2,000 votes so far) currently rates things as follows:
Overnight vigil 24%
Closing Mass with the Pope 23%
Host country/sights/meeting local people 19%
Stations of the Cross 11%
Daily Catechesis 8%
Being a Virtual Internet Pilgrim on Xt3 7%
Days in the Diocese 6%
WYD Food 1%
We've all heard the stories on why the accommodation might not garner many votes (save for the one per cent), but for the story on the food take a look at Psallite Sapienter's Ode to the Pilgrim Lunch (think cold baked beans as a sandwich filling...)! Now I know the Pope did talk about the virtues of asceticism...but there are reasonable limits!
On the plus side, think how much suffering must have been offered up, benefitting the rest of us....
