Can we draw the following hypothesis from the context? 

Context:

By 7 p.m., six of the Saudis left by the newly arrived private plane, flying on to Cairo and remaining overnight until heading back to Riyadh, according to Sabah and other media reports. By 11 p.m., another seven left by the other private plane, heading to Dubai, United Arab Emirates, similarly remaining there overnight and then flying on to Riyadh the next day, according to reports. Two others flew out commercially, Sabah said.

Hypothesis: Just under half of the group ended up staying overnight in Dubai
Yes
