Well, this just goes without saying and this will vary on what part of the country you are in. If you've got to cover alot of ground to get back to your hotel then take a taxi. Travel with friends and just use the same common sense you use at home. Some outfits will add tip after tax. You should tip based on the untaxed subtotal and tip what you would at home.

Patronize local establishments Try to deal as much as possible with locally owned and operated businesses. This helps to keep hard currency in the country instead of having your tourist dollars siphoned back into the USA, Canada or Europe. Eat local fare Always try out local food. Off season versus on season rates There can be a big difference in rates between peek and low season. Hotel rates can also vary.
