Don't worry at all.

Sorry to inform that your info on the infinite pool is plainly wrong, evidence on photo. "Access to hotel guests only, at 400 DHS per person." - approx 40 euros, each day, each person.
The regular large pool, on the other hand, is free for hotel guests.
The inside heated pool, which comes up in several hotel photos, also can be used at a cost - it is not free.

Let me know if you have other doubts, I can assist.
