The group arrived in Giza last Wednesday, and their dream trip soon turned into a nightmare when protestors took over the streets, prisoners were released and people started looting.
"At night we started to hear a lot of gunfire. We could smell the burning of the Giza police station," said Senior. "On Sunday it became clear to me that we, you know, could just not go anywhere, and you sense the anxiety."
They first turned to the United States Embassy in Egypt, but it was overburdened.
"Their advice was to get out of the country, but really that was the only help we got from the embassy," he said.
Senior managed to get the tour group out of Giza with help from a friend in Israel -- a travel agent -- who knew of an Israeli plane that was headed to Egypt to ferry its citizens back home.
"There were only 21 seats left and we were 42 people, and so he argued with them and they sent a bigger plane," explained Senior.
The group traveled through the battlefield that is Cairo in order to reach the airport. He said the scene there was unlike anything he'd ever seen in his life.
Though now safely in Israel, there remains great sentiment, if not for the situation they just left, for the people they left behind.
"The Egyptian people are just beautiful and friendly. They're protective. None of us experienced any hostility against us as Americans," he said.
In a message posted to the group's website, Senior said the group hopes to return to the United States around Feb. 5.
