I'm travelling with my wife and 12-year-old to the Izu Peninsula in mid-March this year. We came up with this plan. I'm interested in opinions about how this seems like it would go, like if we've left enough time for side trips we may discover in the moment or too much time in a place that would be better spent elsewhere. I'm planning to rent a car so we have more flexibility. From what I've read it sounds like the busses and trains on the peninsula may be infrequent in some of the places we want to see.
(When we leave this part of the trip, we'll be heading to Tokyo to do all the big city touristy stuff.)
Tuesday:
1500 - land at Narita, buses and trains to Itō.
1900 - Arrive Itō, check into Laforet Ito Onsen (also considering K's House instead), settle in, get dinner
Wednesday:
0900 - go to Atami and wander (MOA, Atami Castle, etc); rent car at Atami Station by end of day and return to Itō
Thursday:
0900 - arrive at Izu-Kogen for pickup for guided tour of Ike village for the morning
1200 - look for cherry blossoms, wander to 7 waterfalls, zoo, Mt. Omuro (although it looks like this last one may be "meh" according to other opinions here), then back to Itō for sleep
Friday:
visit Panorama Park as early as we can get there, ride ropeway, explore; return car in Atami in early afternoon, then off to Tokyo
