I've recently gone on the Nile and Beyond tour (which includes the Beyond the pyramids tour and siwa tour). I had a great time on this tour and would recommend it to anyone.
Here's some photos and stories from my holiday: Nile and Beyond
Thanks to everyone who helped out before hand (both who worked for Im Trav and those who were kind enough on the forums). This forum was such a great tool of information for me.
If anyone has any questions, just let me know!
