Not likely in any US property maybe a Resort, But the Ren I stay at for 50+ nights throughout the year Overseas has a 15% Service in the rate, so I assume that it inludes tips in a pool kind of way.

didnt know it until I left a tip in the Coffee Shop and the Waitess came after me to thank me, seems the Bills there also had a 15% added on for Service so I ended up tipping Her twice. the next time I ate in the coffee shop I didnt leave an extra tip and she was surprised as she asked me what was wrong. I told her nothing was, only I didnt know the other day that a tip of 15% was added onto my bill already as a tip.
