We are a family of 4 going from Asia to USA next week. We'll be taking various "tours", such as —
- Antelope Canyon Tour (ACT), which is of large tour group type
- Gunblast Vegas (GV), which is of small group type (max 8 people)
The tour price we paid for our family are: ACT more than USD 300 , GV more than USD 700
The question is: Are we really supposed to tip (up to) 20% of the tour price, i.e., ACT = USD 60 and GV = USD 140 assuming their service is acceptable?
Last but not the least, how much would (did) you tip as a local American for similar tours?
