When an Umrah quote says a hotel is close to the Haram, ask how close. The word means different things in different quotes.
Ask for the walking distance in minutes and in metres, and ask which gate it is nearest to. A short distance on a map can still mean a long walk if the route goes around a block or up a slope. Ask whether the path is shaded and whether there are steps.
Think about who is travelling. A healthy adult may be happy with a fifteen minute walk. An older parent or a child may find it hard, especially in heat.
Ask about the lifts and the waiting time at prayer hours, because a tall hotel can be slow at busy times.
