I think the flooring needs a full refresh throughout most Merlin parks. Resin flooring throughout would look far fresher and easier to maintain than block paving, and can be laid directly over existing tarmac.
Overall however, I feel the sparkle project has been a massive success, stealth in particular looks the best that it ever has, even including launch. Quite clear the direction Thorpe are going in, big bright and fun feels, and whilst it is a bit brash, it’s a definite step forwards over everything looking ageing and run down.
I hope Merlin keep this level of investment moving forwards, but also hope that Thorpe gets some more highly themed areas in the future, especially having seen what has been achieved with nemesis reborn.
