I am going to Thailand for the first time in February and am looking for a mix of culture and relaxation. Here is a proposed itinerary, do you think we are trying to squeeze in too much? If so, assuming we want to keep Chiang-Mai, what is the one island/beach area folks here would recommend the most? Pattaya, Ko Samui, Krabi, or Phuket? It looks like I get take a short bus ride to Pattaya from Bangkok; the rest would require a flight?
Day 1 - arrive Bangkok (visit Wat Phra Kaew, Wat Pho)
Day 2 - go to Ayuthaya
Day 3 - go to Chiang-Mai in the morning, walk around, visit the Night Bazaar
Day 4 - stay in Chiang-Mai, visit Wat Phrathat Dol Suthep and Wat Chedi Luang
Day 5 - go to Pattaya (via Bangkok)
Day 6 - Pattaya
Day 7 - go to Ko Samui
Day 8 - Ko Samui
Day 9 - Go back to Bangkok
Day 10 - fly back home
Thanks so much!
