Depends.. there are several options within 20 mins of TDR... and some of them are non-brand locations. I like staying at Hotel Universe.. no frills, small business hotel with tiny rooms, but only 13 mins away by train.
The most popular budget brand is in Urayasu.. those two TDR Partner Hotels.. what's their names?.. I am drawing a blank right now.
^^ Thanks again TDLFan. If / when I make it over to TDL I would have an easier time justifying a place like that to myself, though the urge to splurge on Mira Costa would be quite strong. Are there any family-run or B&B-type hotels in Tokyo you are familiar with?...some greater cultural exposure being something I might seek since I doubt I would get to visit Japan very many times in my life.
