The short version
Songkran is Thailand's New Year festival, and Pattaya is one of the three biggest places in the country to be for it. For three to five days in mid-April, the city runs water fights at scale — Walking Street, the beach road, and every neighbourhood in between. The festival is genuine: it is also, in Pattaya, genuinely enormous.
Most groups base in Jomtien and treat Walking Street as a day trip. The logic is the same logic that makes Jomtien the right side for a Pattaya group trip during quieter times: close enough to be five minutes from anything, far enough that the compound stays calm after 2 AM.
