5: England + Wales
Numbers 1 to 3 fell in to place pretty quickly, 4 and 5 were more of a competition. Number 5 came down to between this trip, and one starting in Toronto, and heading South to the North-Eastern United States. In the end my own personal patriotism won out.
This trip involves a large circuit of England and Wales, taking in most of the major parks along the way. I did consider a diversion to Scotland to do Loudoun Castle and M+D''s but thought it was to large a diversion for this route. There's also quite a few extra small parks you could do on the way if you had time, most noticeable East along the coast from Paultons Park.

4: Scandinavia + Russia
Scandinavia is an area regarded as one of the great hidden gems in the world of amusement parks. Despite having loads of friendly and hospitable parks, and some very noteworthy rides (including my all time number one coaster, Balder in Liseberg) the parks here don't get that much worldwide recognition outside the major coaster enthusiast community.
This route secured it's place at number 4 when I looked at the maps and realised you could also visit St Petersburg and Moscow. As well as visiting the main parks mentioned here, and some of the smaller ones in these two Cities if you have time, you'd also get the chance to visit some very interesting parts of the world.

3: Japan
One of the main reasons I ranked this at number 3 was because Japan is one of the main countries in the world I'd like to visit some day that I haven't yet visited. Not only that, but Japan has a huge selection of parks, including a 4th dimension rollercoaster, and the worlds tallest chain lift powered coaster. It wasn't until I started researching this feature that I realised just how much Japan has to offer the coaster enthusiast. The main area is around Tokyo, which has two Disney parks and quite a few smaller parks within the City, plus a good number of notable parks within day trip distance. The ultimate trip though would be to drive across Japan sightseeing and visiting the various parks along the way.

2: Belgium, Holland, Germany and France
There are quite a few possible trips in Europe. I've already mentioned Scandinavia, plus parks located in Spain and Italy could form the basis of a good trip. I think the ultimate European trip though would take in Germany and Holland. Not only do they have some of the best parks on offer, but they also have parks with a unique European character to them. Ideally I'd time a trip like this to also include one of the major German fairs at Stuttgart or Munich.
Here I've extended the trip to include Belgium and France, to make it one you could do by getting a ferry across the channel and back. Although the time taken to do a full trip like this wouldn't be easy to come by, a shortened version of this trip is a genuine possibility.
