A great way to travel with kids, especially if you plan to stay long enough aborad, is house / appartment swapping. Find a foreign family who'd like to come to Vegas for a few weeks or months and exchange houses! This way, your kids will have a real place to stay (more comfortable and personal than a hotel room), with their own bedroom, they'll find toys... etc...
I went to Quebec like this with my family when I was 13 (my youngest sister was 7) and I loved it!
There are several websites that will help you put such a project together.
You should know that it's not possible for Japan, though (it's illegal to subrent or host someone in your appartment if you are not in it) |
