Please contact your bank and let them know you will be traveling in Thailand and may be using both debit and credit cards. If your bank doesn't know, they may block access to your card while you are here. On this note, there's no need to bring large quantities of cash. There are plenty of ATMs and we will make stops for you to take out money. We suggest that each traveler allocates $100-200 for the entire trip. Most places only accept cash (Thai Baht).
We would recommend tipping your Discover Corps Guide around 1,000 - 2,000 Baht (~$30-$60) per person for the duration of the trip based on what you feel appropriate after your time in Thailand. You can leave this with your guide on the last day prior to departure.
Please note that we do include tips for restaurants, local guides, hotels and porters!
