Sanity check short itinerary for solo rider

[Rodney Munch]

Hi everyone. Long time lurker, first time poster.

I was hoping to sanity check my planned itinerary to make sure I'm not biting off more than I can chew (or am I not biting off enough?). I'll be travelling solo.

Day 1 (very early November): Arrive in Marrakesh
Day 2: Collect rental bike (Himalayan 411). Marrakesh - Ait Ben Haddou (~200km)- sticking to the google maps route.
Day 3: Ait Ben Haddou - Tagounite (250km). Again on the google mapped route.
Day 4: Tagounite - Erg Chegaga (~100km). Planning on taking S2 from "Morocco Overland", taking the moto out by Erg Lihoudi and overnighting in one of the glamping spots by the Erg.
Day 5: Erg Chegaga - Foum Zguid (~100km). Finishing off S2.
Day 6:Foum Zguid -Taliouine (190km). Reversing A4 from the book.
Day 7: Taliouine - Marrakesh via Tiz n Test (240km)

Does this all seem achievable? The biggest quesion is the sand on S2 - though hoping by breaking it down into a couple of days, it'll become a lot less stressful. I've limited off road experience other than a few days green laning and a few enduro days (on a DT125 and a KTM 250) but none in sand. I ride ~18,000km a year on road at home (NC750).

Am I wasting potential with the first 2 days just blasting down south?

What apps are people using on their phones for navigation by GPS coordinate. I'd like simply an arrow and distance to each weypoint (from the MO book) rather than following a bread crumb.
