Try again, Tripsdrill has the original bathtime themed log flume attraction... Including animatronic half naked ladies...
And personally I'm not bored with pirate themes... Towers were clever with it as an addition as it didn't require too much work (with the pre-existing buildings already being piratey), pirates regaining popularity due to the films, and it actually looking pretty decent and revamping a rather dull area by giving it a much more obvious identity...Pirate themes are also very simple for guests to understand, as they are very general knowledge... That's why lots of parks have them... Nice, simple and can be very effective if done well...Replacing Flume does provide an interesting choice for Towers, removal could involve a good old arguement with the council, whilst revamping would be the cheapest idea, but not provide anything truly exciting and new... Plus they will need to consider throughputs as Peter said, it's one of the highest in the park...A conundrum...
