I wanted to add the Railway at MK, for a full trip around the park but there seems no options for this. The only option is the railway stations, all four and if you add all 4 it adds 4hours of time for my plan. Any suggestions or idea. thanks.
Add a break for 45 minutes and just note what you're doing. That gives time for waiting for the train and doing a complete circuit.
Just add one Railroad Station, not all 3. The plan assumes you are doing one whole lap, which takes about 20 minutes. If you listed all 3 stations, it is actually way too much time (3 times).
Unfortunately, they do not yet have a way to select just a short segment. People do just one or two segments as a transportation method, not just an attraction.
