I think Thorpe Parks next 10 years looks so promising!
I'd say yes and no to this one.
When you look back it was only in the early 00's that we saw rapid expansion/change at Thorpe, Tussards were installing very large rides to significantly change the park into what it was today. For example:
2000 Tidal Wave
2003 Nemesis Inferno
With the massive number of new attractions being installed, they sell themself, people look at the new rides and want to go. Now with Merlins high/medium/low investment years, we are likely to only see a major new ride every 3ish years and maybe a flat every 3 ish years with a touch up of paint on the low investment years.
Add to the fact that Thorpe seem very keen to add a full blow hotel, you can bet your bottom dollar that one of the large investment years sometime in the next decade will be a full hotel.
There is no doubt that Thorpe will continue to expand, but they can only really install two more major coasters before they have to start ripping out what they already have. A major positive for Thorpe is the number of potential locations for future flat rides and the not so strict local planning permission situation.
What will we see at Thorpe in the next 10 years?
-1 Major coaster
-1 or 2 new flats
-a 100-150ft sky swing
Merlin will expand the park and we will see it grow, but it will be done at a much more slower rate than we saw in the early 00's.
