When you make the intention to travel every trial and struggle that comes your way is a test from Allah subhanahu wata'llah especially when making intentions for Umrah and Hajj. So while DST may have some problems here and there, the Hajji (which is you) must react with patience and humility. Any misreaction from you such as anger, annoyance, backbiting (with your heart, mind, or speech) etc etc. and Allah subhananhu wata'llah may remove the blessing of your trip. I have found that for every problem there was always a kind and patient person willing to help. SO if you would put aside your petty squabbles and pseudomiseries, focus on the true reality that is potentiality of Heaven or Hell, then you'll realize that these issues are mere small discomforts when compared to infinite torment. InshAllah may Allah save us on that day and may he make travels smooth and pleasant for everyone :)
