“So much of who we are is where we have been.” - William Langewiesche
Be Flexible and Have Fun. That way you won't waste time being in a bad mood for something that didn't work out as planned but instead you will have the opportunity to focus on the positive side.
There are no silly questions! You will have a clear vision of your trip when you know more.
Take pictures of your luggage and clothes. It will be easier to communicate with your embassy and reclaim your luggage in case you lose it.
