If you are going with other persons, then take care they are good people.  A corporation makes a man, and it’s factual when you are in the blessed sites too.  Having good corporation can create a permanent impact on your Holy Travel.  Are the people you are with going to boost you to pray Tahajjud in the Haram and do additional tawaf or are they going to in its place encourage you to eat the 4000 calorie dinnertime from McDonalds at 2 am so you practice a food coma and have anxiety waking up for fajr?
