Tipping isn't something that always comes logically to us Kiwis. Sometimes we need some help to figure out what we should be tipping in general. But Tipping at the end of the day doesn't have any strict laws or set rates, it is measure of the service you think it deserve so take the following figures as a guide for your next trip to America.
Taxis and Hotel Shuttles
For taxi drivers you should tip 15% of the cost of the trip at minimum. If you use a courtesy hotel or resort shuttle, $1-$2 per bag is appropriate or $5 if you have only carry-on luggage.
If you utilize a bellman you should tip at least $2 per bag
No tip is required for the staff member who checks you in
Generally no tip is required, but if a special service or special reservation is secured, a tip is always welcome
Hotel Housekeeping Staff
Generally tip $2 per day and more if housekeeping does a really excellent job
Read your room service menu carefully. Most resorts build in a 15-20% tip in the bill. If not, then add the appropriate tip.
At a Restaurant or Bar
If you are dining at a sit down restaurant or drinking at a bar, a tip of 15-20% is appropriate. If you are eating at a lunch stand, shrimp truck or any similar take-out location, they will generally have a tip jar where a couple of dollars per person is appropriate. There is no need to tip at fast food restaurants, eg McDonalds, KFC etc
Tours - General Guidelines
1-2 Hour Guided Group Tours
A tip of $5 per person minimum is generally appropriate
2-4 Hour Group Tours
A tip of $10 per person minimum is generally appropriate
4 Hour to Full Day Group Tours
A tip of $20 per person minimum is generally appropriate
A tip of $10 per person to the pilot for a one hour flight is generally appropriate. If the pilot is very friendly and especially knowledgeable, generally tip $20.
Most sailings last 3-4 hours, less for a sunset sail, as a guide - $10 to one of the crew upon departure, more for longer sailings or if the crew has been especially helpful
You will need to decide what you feel is appropriate based on the services rendered. Here the 15-20% rule is generally applicable.
