Your way: Having rides which you deem suitable for the Chessington market. According to yourself, Rameses isn't suitable for the market. I presume Rattlesnake wouldn't be either in your way of thinking.
Well, this is how chessington decided to go once Tussauds bought Thorpe Park. They removed Samurai, replaced it with peeking heights. They introduced hocus pocus hall, built land of the dragons, put sponsorship into Bubbleworks and completely changed their branding and identity to fit within these ideas.
Result?: Huge loss of custom, huge brand clash, lower guest satisfaction. Until merlin came in and gave the park direction again.
