As a single female traveller, i find pocket wifi good to have. Eliminates some of the stress in case sometimes directions we got earlier are not as clear as i thought, then again maybe i hv lousy sense of direction. But for me its just useful. Since no one to discuss if unsure, it helps to be able to look things up immediately. Also sometimes want to look stuff up that may not have been covered during preparation.

That's just my 2 cents worth.
