The populations around a park are really interesting - to me at least. Here's the population density within x km of Disneyland Paris, US Orlando, and proposed US GB. All three have very different profiles for local populations.
- The proposed GB location rises sharply with distance beyond 50km as London and Birmingham come into contention, which explains the 2 hour travel stats (50% of population).
- Paris is on the doorstep of DLP but falls behind the proposed USGB location at around 70km and ends up with many fewer within 2 hours (though the toll road system in France means you can cover distance v fast if you pay).
- Orlando has a good population very close but a very small population outside of the immediate environs.

Public transport also interesting - this is for trains but bus stops have the same pattern:

This might be of zero interest, but for me it helps to understand the logic of the location - small population within 30 mins door to door with proposed GB site, but enormous within 60-90 minutes.
There is likely a probability distribution that I could use to weight probability of visit based on distance - if anyone knows of a data source for that I'd be keen to work it into calculations. Data source I have is limited to 100km, but taking this as the maximum radius 22-24 million is the most you can get within 100km in the UK, and to get that you can build a park anywhere in a triangle defined by Oxford, Bedford, and London. London-based parks will fall behind at >100km as you're entering the channel and not yet reaching Birmingham, so it becomes an arc between Oxford and Bedford that have maximal population catchment at 120km. Major options in this are Oxford, Milton Keynes, and Bedford - Bedford has best airport and train connections of those plus probably cheapest most plentiful land.
Interestingly, I can't find any other area in Europe with a population approaching 22m within a 100km radius (100km probably being about 90 minutes drive allowing time to get to a major road). Most major population centres in Germany and France seem to top out around 15-16m in a 100km radius, thought I've just been randomly selecting areas of highest population density (just found building near Eindhoven gets you 20m as you get both Amsterdam and Dusseldorf).
