Weather and time of day permitting, I do believe a tour would/could include the outdoor areas. It is my understanding that use of them is restricted to hotel guests (although, you probably could include a dip in the pool with a bungalow-type party).
Regarding “certain moods or mindsets”…keep in mind that no sexy-time activities can take place outdoors. Much to the chagrin of the nature-lovers among us.
Also, tours are often a way to transition from the initial meet & greet, into a party…sort of a decompression chamber, so to speak, where you can chat, see everything, and perhaps from some coherent thoughts before diving into a negotiation.
Best of luck!
