Sorry to interrupt QF WP, but as we know
@rainbowgirl is contemplating a trip to the US, I thought I should point out that in most cases of shuttle bus drivers, waiters, bag carriers etc, a tip
is generally expected. Sometimes its actively solicited (a bus announcement ... 'tips welcomed, folks'), other times its added to your restaurant bill (note: tip only for the food & bev supplied, not on the tax !), or you get a 'choice' when using your credit card on the machine. Often its passive though and a minefield for Aussies (traditional non tippers) especially. Rainbowgirl, take and keep a supply of US$1 bills handy for tips. if you do go to the US, ask more about tipping in your thread.
I think at Disney though they don't tip on the shuttles?
Sorry again QF WP, looking forward to Seattle
