Need your help with trip planning.
First of all we're family of 2 adults and 2 kids (boys 10y/o and 13y/o).
We've been to Tokyo and Hakone before but this time around we want to explore a bit and venture outside Tokyo.
We arrive at Tokyo on March 30th and leave on April 11th 2018.
We do want to spend a few days in Tokyo as we want to have an option to go to Nikko/Kamakura/Disneyland.
We do want to visit Osaka (Universal studios included), Kyoto, Nara, Nagoya (The new Legoland). Am I missing anything?
Since our flight is to/from Narita we're in a bit of a dilemma as to where to start our trip and how long to spend at each place.
Do we fly from Tokyo to Osaka and use it as a base to venture to Nara/Kyoto/Nagoya or go by train on Tokaido line from Tokyo and stop in Nagoya/Kyoto/Osaka and then back?
Do we do it on arrival to Tokyo or spend a few days there, then Osaka, then Tokyo again for departure? Ideally would like to spend at least one day in Tokyo before departure (just in case).
Or may be it make sense to buy JAL explorer pass and fly from Narita to Osaka and back?
What itinerary would you build (We've never been outside Tokyo). Just to complicate things more - my wife likes amusement parks and I love temples........
What is cheaper/better/easier/make sense for 3 adults and one kid?
A lot of unknowns but since it's a cherry blossom period and it's Japan I need to book accommodation earlier (it's expensive as it is already) before it's all booked out
Thanks for your help in advance.
