The way I see it, we'll never learn anything if we don't know what we're in for.
Every trip I've had since '99 has been getting better and better since I am more prepared, thanks in part to these boards. (Eg. I would never have asked for a Concierge upgrade at any hotel but since learning it was relatively cheap at the WL, why not?)
I am more prepared now more than ever because I have learned from other people mistakes. And guess what, Im looking to improve our holiday all the time, so why not take advantage of these learning opportunities.
As much as we'd like to know about the bad stuff. Writing sentences like 'Little Johnny's vomit was combination of chilli cheese fries and the casserole we had at Resturant X just a few moment earlier. It smelled pungent and overtook the room with a stench strong enough to peel paint' etc. I very much believe you can subtle without being overly descriptive.
To JennyMouse I say 'Bring it' but remember just because its bad doesnt mean to have embarass yourself. In my latest TR, I like to think I was very tactful by implying I had diarrhea without actually using the word or getting descriptive.
If you had problems, I'd love to know, what caused it? Could it been prevented? If so how? How did you resolve it? What were the costs (Time, money, people (going home, to hospital etc)? Looking back, what would you do now knowing what you know? Any outcomes (Never going to Restaurant X again, Reporting CM to Manager, drinking bottled water, using own transport)
Look forward to that TR!
