As far as i know, they offer daily meditation classes. But consecutive 2-3 days, not really sure. You can contact the staff through phone and email. The info are listed on Wat Mahathat website

The meditation classes are from 7-10am & 1-4pm daily. But it’s better to call the center first before you go as they might have cancel the class for some days. As for whether it is suitable for kids, it’s also best to ask the center.

Any answers? Am also quite interested:)

You would have to check if they have availability in Dec. I expect so. allow for extra time to find the building, ask people at the temple for the easiest way to find the building. Its a bit hidden in the complex. yes it is good for beginners. wear comfortable clothing like yoga pants or althetic wear as you will be sitting for long periods of time. No shoes will be allowed in the studio. bring water. a small dollar amount for donations is appropriate. $10 or $20 usd is more than enough.
