Understandable, are there any specific network requirements that this 
Dante requires? Also what is the bandwith we can expect? Based on a 
quick google we would prefere that you use the unicast routing/ dataplane.

We will take this into account with the planning, but no guarentees 
about PoE availability in those location yet, altho mostly in tents we 
plan to deploy something with PoE because of the wifi accespoints.
For my information is this one port where you will then chain more 
switches behind or these are all the ports you will need for the Dante 
stuff?

When we have finalised the inital plan we will let you know.

Be aware that running your own wireless networks is not allowed.

Where would you want this drop to be exactly? For the internet access a
normal visistor port should be sufficient.

This depends on the location and with what speed you want to connect.

Both are fine, what ever works for you the best.
