Detailed view on calendar

Hi, I'm trying to do the following.
I have a reservation with two dates, a "check-in" and a "check-out" in which there are people who participate. These people are in the "persone" database and the dates are in the "rPrenotazioni" database. For the moment everything is connected but I would like to see in the calendar the entire period from check-in to check-out with the names of the participating people an the color of "Fase di".

So I need to see this on my calendar:

The event from start-date to end-date in the color of the field FASE DI and as text on it has to be :

FASE DI+ EVENTO+ COGNOME.

If you check the record in the image I need to see on calendar:

MONTAGGIO- ALLES FUR DEN GAST- Tessadri, Bellini, Walcher, Sartori, Hofer, Ralser, Lorenzi Dimitri

in RED COLOR

Thanks for any help..I know it's a mess :P
