Ran this twice, 1st for new players in person, 2nd for veterans online.
Both times went great. The module has very clear goals (reach Parnast!) so the party has a good idea of how they're progressing at any time. The loss of the drivers, camels, and potentially caravans are good indicators of how well they're doing overall too.
Adding some personality to the random merchants/drivers did a lot for both games- rolling on NPC generating tables and doing some light RP between them and the players made their deaths feel more tragic.
Only part that played awkward was the scene with the cloud giant castle- just make sure to clearly describe what physically surrounds them, so they can begin scheming how to handle it.
