Is the Grand Egyptian Museum worth visiting, and how much time do I need?

Absolutely — the Grand Egyptian Museum (GEM) sits right next to the Giza pyramids and is now the largest archaeological museum dedicated to a single civilisation. Plan for at least 3 to 4 hours; the full Tutankhamun collection is the highlight. Go early to avoid the midday crowds, wear comfortable shoes, and consider pairing it with the pyramids in the same day since they're a short drive apart. Tickets are cheaper if bought at the entrance or online in advance.
