Listen, I don't want to be a "party pooper" here...

and spoil the mood I hope I've hopefully managed to get you into,

but whenever you have the time, you should maybe read

the "Why you should hire a licensed-guide" page in the "Good to know" section.

And it so happens that, at the Catacombs, only a guide can bring you to the restricted areas. I thought you should know.
