If you have less time, consider cutting down on the activities and focus on exploring one or two cities. For those with more time, add in some adventure tours such as zip-lining in Chiang Mai or bungee jumping in Pattaya. Ensure that you carry enough cash with you, as many of the places on the itinerary do not accept card payments. Most importantly, have fun and enjoy your time in Thailand!
