Heads up though, Drayton Manor's website states "Full park reopening 24th March" when the main season begins.
It also states that March 10th is "Thomas Land only" which implies that the rest of the theme park will not be open yet, so you won't be getting the full theme park, just the Thomas area for younger kids and the zoo as well, so no Vikings area or Adventures Cove area, no Accelerator or Bounty rides, etc, and definitely not their new coaster which is still being constructed.
