Tokyo DisneySea Hotel MiraCosta is located partially within the incredible Tokyo DisneySea theme park and has an Italian theme to it. Areas of the hotel are themed to an Italian Mediterranean sea port. It overlooks the Mediterranean Harbour section of the park.
It’s usually the most expensive of the 3 hotels at the resort and near impossible to get a room from what I’ve heard. I wouldn’t know personally as its well outside my budget to stay here.
The cheapest rooms in the quietest times of year, which only sleep 3, start at 36,000 yen, around $NZ390 or $US305. Like at the Disney Ambassador Hotel and the Tokyo Disneyland Hotel, at the busiest times of year, you will pay half this again. There are other category rooms which sleep more people, or are in better locations or themed rooms, but you will start paying around double this price.
