For a lunch before joining, the Baan Thai Food Museum opens earliest at 11:00. Garden Cafe on Beach Road serves sets from 12:00, a fit for a meal before stepping onto the Wan Lai streets.
For the midday water-fight hours slot in somewhere with a cold drink, such as the Kliff Beach bubble set (12:00-17:00) or Barracuda tea on Akara's 24th floor (13:00-17:00). April reaches 35-40 degrees by day, so rest is needed.
Dinner after getting soaked splits among Jimmy BBQ and DAM at 17:00 and All Star Cruise at 18:00. For a filling group meal, Jimmy BBQ; to sit late, DAM until 23:00; for night views at sea, All Star Cruise.
If you spend time near Tiffany's Show, Thai Marche is open 15:00 to 22:30, fitting a meal before or after the show. One set per person is required.
Before booking, check Songkran surcharges, the cruise ticket exchange time and the late-table rule on each listing. Wan Lai is crowded, so allow generous travel time, and hours and menus may change.
