Can she go from the hotel to the Haram and do tawaaf without a mahram?

Question

Praise be to Allah.

It is permissible for a woman, if she is
in Makkah, to go walking from the hotel to the Haram without a mahram, and
to do tawaaf likewise, because it is only necessary to have a mahram for
travelling; inside the city it is not essential to have a mahram. Rather
what is stipulated that a woman should feel safe in going out and not go
out wearing adornment or make-up.

The same may also be said concerning her
going to stone the Jamaraat. She may go there without a mahram; she may go
on her own or with a group of women.

If a woman is in one city and wants to go
somewhere in a taxi, it is stipulated that she should not be alone with the
driver (khulwah); if there is a righteous woman with her, then she is not
alone with him.

Shaykh Ibn ‘Uthaymeen (may Allah have mercy
on him) said: With regard to khulwah (being alone with a member of the
opposite sex) inside the city, it is not permissible for a woman to be alone
with the driver in a car, even for a short distance, because the Prophet
(blessings and peace of Allah be upon him) said: “No man should be alone
with a woman without a mahram being present.” But if there is another woman
with her and the driver is trustworthy, then there is no khulwah and there
is nothing wrong with her and the other woman travelling in the car, so long
as their trip is not regarded as “travel.” In this case, we may say that
there is no khulwah because of the other woman who is present. But we cannot
say that the woman who accompanies her is regarded as a mahram; rather we
say that what is forbidden inside the city is a man being alone with a
woman, unlike travel, in which case it is forbidden for a woman to travel
alone without a mahram. The difference between these two matters is clear.
