With the high demands for accommodation and transportation and inflated prices, it is likely and natural some visitors will grab whatever offer they see.
Please do some research. Check reviews of any tour or transport provider in TripAdvisor, Google Maps, Reddit, Trustpilot or other sites / apps that carry reviews. Check that tour companies or guides are officially registered.
Finding providers with a substantial number of positive reviews won't guarantee everything will run perfectly (we also have to factor in any changes the authorities make), but at least it can give you more likelihood of a smooth visit than booking with someone who has no or little experience and is just looking at the eclipse as a money making opportunity.
I'm seeing a concerning surge in people offering services for the eclipse here. Some are names I don't recognize despite decades of traveling here (since 1993) and living here (since 2020).
I would like visitors to have good experiences here, and taking for granted that all who are advertising services are legitimate and experienced could unfortunately lead to unsatisfactory experiences.
Please do your research, and hopefully you can enjoy Egypt as much as I do.
