If you are decided to spend your time visiting and exploring tourist destinations during your holiday travel, then I recommend you to get up early in the morning. You are not there to sleep and will beat the queues as most people won’t get up early!! Calm down and try to be nice and smile if something goes wrong; being kind and patient is the best way to get help. No one is going to help you if you flip your lid at them. I understand why you might want to, but it’s not the best solution.
