Yup. I see the usual 2500s pulling some massive travel trailer and figure they are getting 10-12 mpg, same with a motor home. Then they are towing some midget car usually. I'll just stay in a hotel.
My wife notes it would mean she'd be cooking and cleaning as if she were at home.
Our hotel in Tokyo is $861 per, but I managed to use points. As if.
A cruise with the uprated balcony suite runs about $900 per night, not including excursions (tours) which get pricey.
A "normal" driving trip runs maybe $250-300 a day for a decent hotel, food, and gas for two people.
Travel is expensive unless you use rail and hostels etc.
