Find accommodation in Uthai Thani
As said, there are many Thais, especially from Bangkok coming to Uthai Thani on weekends and public holidays. Even if they do not book in advance, the hotels and guesthouses in Uthai Thani are often full from the beginning of the afternoon on those days. That's why I advise you to book your accommodation in advance if you are planning a stay in Uthai Thani over a weekend or holidays in Thailand. note that among the accommodation options in town, you have a floating guesthouse or a hotel by the river 5-minutes away by bike (provided for free) from Wat Bot and the town (see my accommodation recommendations in Uthai Thani).
