How To Tip

So after nonreving to that great destination or cruise, It seems like everywhere you go someone has their hand out looking for a tip. The question is how much will make them feel that they want to help you when you come back without spending all the money you saved. A while back we told you about what each country's tipping philosophy around the world  is, now we are going to break that down further for each service you may use. It is in dollars so you may have to convert the currency which we have on each individual Nonrev Pages.

 

  • Taxi 15% - This one shocked me. All these years I thought it was 20. Here is another tip to make sure they take the quickest route. Have a map out and ask questions. This will make them think you know where they are going and they won't do anything to lose a tip.

  • Limo 20% - since you don’t pay them by the mile, the tip is dependent on the other services like how safely he drives and how prompt and polite. It also depends of any extra things he brings for you.

  • Bellhop/porter 1-2$ 2 for the heavy bags. This of course depends on the currency of the country. Those with a weaker one may expect your currency over theirs. Stay away from giving change in a foreign country. It is much harder for them to convert or for them to use.

  • Doorman 1$ for hailing a cab. If he just opens the door, a thank-you will do. If it is more than that, like holding an umbrella, getting a cart for your bags, or helping with bags, a tip is good manners.

  • Parking Valet - 2$ This tip is only paid on the return of your car, in good condition. If special care is required like with premium spot or if it is very expensive, 5-10$ for both dropping off and picking up.

  • Room service - The first thing to do is look for service charge. If there is already a charge, then you are not obligated. If there is some kind of set up or special handling you can't do, then tip 15-20%.

  • Housekeeper - For extra soaps or folding towels into swans like on cruise, anything above and beyond, 1-2$. It is very important to put the gratuity in envelope clearly marked and sealed so there is no confusion.

  • Concierge - There is no tip for ordinary advice like directions or simple reservations. If they get a special reservation, then it is 5$. If it for hard to get tickets, it is 20$.

  • Pool attendant - No tip is needed unless extra service like reserving lounge chairs, lending reading material, inflating pool toys, or providing sunscreen. Then it is customary to tip 2-3$.

  • Tour guide - First check and see if a tip not included. If it is not, then a gratuity of 10 to 20% is customary. If it is an  all day tour $3 to 4$. If you are lucky enough to have a private tour, more is expected.

The other thing about tips is if you currency is stronger than theirs, it is fine to use you money. Just don’t give it to them in coins less then base currency. Giving 4 quarters in Haiti is useless because they have a problem exchanging it. A Dollar or Pound or Euro is accepted universally.
