Going to Bangkok-Ayutthaya-Kanchanaburi-Koh Samui-Koh Phangan

Hello everyone.
We are planning a trip in Thailand for around 9 days. This will be our first time travelling in Thailand, and the first in Asia for a few. We are a group in our late 20s (26-29). We are interested in seeing some cultural and nature sites, temples, night markets, street food, seeing local life, floating markets, etc.
We will be arriving in the early evening on May 17th in Bangkok and leaving on May 26th from Koh Samui.

Our tentative itinerary is the following:
May 17th evening - check in-to hotel. Catch a meal at the night market (or Khao San Road). We would like to see how bustling a touristy area can get but will not stay in this area.
May 18th - Chatuchak Market in the AM (is there anywhere else we can go near the area in the evening? or would heading to the malls be a better idea since we may be tired and adjusting to the weather.
May 19t h-Temples tours along the canal. Not sure where would be a good area to relax in the evening or grab a few drinks. Is Chinatown worth a go?
May 20th - Head to Ayutthaya for the ruins-drop off the luggage at the train station. Will try an elephant tour of the ruins and head to the floating market./Japanese Garden, etc. Then we would like to head off to kanchanaburi for the evening.
May 21st-a tour around kanchanaburi-death railway, falls etc and then catch an overnight transportation to surat thani-koh phangan
May 22- Koh Phangan
May 23-26 Koh Samui (one of the days, to do a day trip to Angthong Marine Park.

Would this sound too packed?
How can we transport ourselves from Ayutthaya to Kanchanaburi and from Kanchanaburi to Surat Thani?
Do you think we should make any changes to the itinerary?

Thanks!

Would this sound too packed
Yes - drop the specifics and just enjoy where you are
the only need for dates is so you can all agree what town you will be in

you are trying to squeeze too much in on almost every day.
eg: 20th - temples? takes all day or even two days, floating market? takes all day, travel time from china town to Ayutthaya plus travel to market plus travel time to kanch is probably about 6 or 7 hrs as well
It just can't be done unless you turn up take one photo and move on
21st - the travel times involved are too big. One day in Kanch, one day in Sai Yok, next day on the train is 3 days

There are buses from Ayutthaya to Kanch and from Kanch to Surat Thani

#1 Ayutthaya to Kanch - very few if any direct buses you will need to change at Suphanburi
Kanch to Surat Thani again very few if any direct buses will need to change in Ratchburi at least and personally I would get the train from Ratchburi

Agree not a chance of doing this using public transport. Cut out either Kanch or Ayutthaya

^^that's not advertising that's telling him where he can read about all the places hes asking about - TT's getting bloody worse!
