Well 8 years ago and now not same, covid messed up a lot events and lot of places still shut.
Muang Kao is still relatively quiet in the daytime and evenings.
It is very busy around the Historical park area during this holiday period as always.
Weekends at the park can be busy sometimes as well all year round.
No parties on a big scale anymore like there use to be only people's private parties.
There's a market in the park at night until about 9pm.
I would have to find out when park stays open at night and puts lights on around the main temple areas.
It was every Friday and Saturday evenings.
As a rule Muang Kao ( Old Sukhothai ) and the park are all shut down at 9pm and the only activity is around the two 7-11 shops.
New Sukhothai has new beer and snacks places built and live music but the music mainly caters for the young.
There are many restaurant places open and scattered about the city.
Our recent visits to Chopper bar showed it not to be busy at all, Friday and Saturdays seem to be the only busy times they still have a one man band live music sometimes but play western music over speakers mostly.
There's the Heart Lake area that use to have concerts, again I would have to ask somebody.
You mentioned Phitsanulok that is a much bigger city which has numerous places to go.
