We're planning to go to Kawaguchiko this November and would like to know what is the most economical plan to go there from Shinjuku. We plan to use the retro bus to explore the fuji five lakes area as well, so if there is a plan that covers round trip Shinjuku-Kawaguchiko + retro bus, that would be the most ideal.
Also, is it better to stay one night there or is it enough to make it a day trip from Tokyo? We're coming at the end of November when the autumn leaves will have already passed.
Inputs are very much appreciated! Thanks :)
