There's a shop there where you can hire a racquet but its rarely open these days so we suggest you purchase one for yourself beforehand or ask in the Facebook group if someone will bring a spare one for your to borrow.
Sports World in Kad Suan Kaew is a good place to find racquets and other gear at reasonable prices.
