If you are taking a tour by bus, it is customary to give an expression of thanks to your guide (around of $10-$15 per day per person) and your driver ($3-$5 per day per person). It is common to tip the wait staff at restaurants (about 12-15% of the bill) and bellboys at hotels ($1-2 per bag).

*Although this is the standard tipping procedure, each country can vary. You can always tip more as well for exceptional service!
