In short: The cheapest room is not always the least costly stay for your party.
Calculate the real saving
Compare room costs for the entire stay and all rooms required. Then subtract any additional transport costs from the apparent saving. For example, saving SAR 120 per night over five nights creates SAR 600 of room savings; additional taxis and other expenses reduce that amount. These numbers are illustrative, not hotel or taxi rates.
Ask what you would do if the included shuttle is busy or unavailable at the time you want to travel. A budget that depends on never using another option can be fragile.
Compare the journey you will repeat
Map the route from the actual hotel entrance to the access point you need, rather than measuring to the mosque boundary. Include lifts, road crossings, queues and any remaining walk after a shuttle stop. Routes and access arrangements may change, so verify the details close to travel.
Consider how often each person expects to return to the room. A location that works for one long outing may be less convenient for several journeys with rest breaks.
Choose the trade-off consciously
A farther property may offer more space within your budget. A nearer property may let family members rest independently. Neither choice is universally correct. Put the maximum walking tolerance and preferred transport arrangement into your trip brief so providers do not optimise only for room price.
