In fact, travel is always a time for relaxation and entertainment. 
If there are legal casinos in the area where you are traveling, then of course why not go to the casino even if you have never played in a real casino before.  You will immediately feel the difference with how to play online and how it happens in a real classic casino.  I assure you from my experience - you will like it.  And the mood will immediately be great, but of course if you stop in time and do not lose more money than you can afford.
