Rabat works well over 48 hours: Oudayas and Hassan Tower on one side, Agdal dining on the other.
Day 1 — medina & Oudayas
Morning at the Oudayas, then Hassan Tower / mausoleum. Lunch in Hassan. Late afternoon in the lower medina if crowds allow.
Day 2 — Agdal
Café on Fal Ould Oumeir, then Italian or rooftop dinner. Rabat-Agdal station links Casa and Kenitra easily.
