Just post what is the job, it'd be better for everyone.
There certainly is a big difference between traveling and being a tour guide.
for business or for travel？ 入境的时候被问过不？
business trip is very very tiring,esp u just get to a city,travel to the place u r going to,talk,business,done,switch to another place :(
so staying for a while would be perfect
If you travel too much for touristic purposes you will feel keen after some time to do something useful again. Ask all those people who were on the road for more than a year.
