Sorry to drag the Beach in here, but it used to be a top notch hard rain attraction...
Over time admittedly...
Noah's Ark, so appropriate in an all day shower, as we call them on the Fylde...
Then an hour or two in the Funhouse.
Then admire the nice roofwork on the derby racer, alice, ghost train, river caves, space tower, camera obscura, goldmine and monorail.
The majesty of watching Poirot in his gondola, in the Blue grotto of Capri, as the river caves young lovers sail past below, and the Goldmine rolls by at eye level...eating a cream tea on the Magnolia Cafe balcony, genuine twisted corn railings from the southern states to highlight the power of king cotton in Lancashire .
Same slow tune for decades...steam rising from all the wet coats seeking shelter, forming a mist on the river caves lagoon.
Space Invader for the coaster freaks, covered carriages on the train, then the nice covered cablecars from the space invader back to the entrance.
Tom Sawyer rafts had a nice roof as well, twenty minutes shelter on there if you managed to miss the logflume boats splash.
Fifteen reasonably dry attractions, a dozen bars, arcedes aplenty, sheltered gamestalls, and covered seating and eating in half a dozen differently themed places around the park, american diner, bean st, cresta cafe.
It rains sometimes in Lancashire.
Wet days on the Beach...Crevettes balcony has a canopy, the staff have hot water bottles.
Love it in the rain...the coasters are faster, the queues are shorter.
And skin remains waterproof, for long periods of time.
