@Wende2 The map doesn't sound crazy at all- and the hummingbird feeder is cool. I don't need a feeder where I live- I have a plant that the hummingbirds love right next to the outside dining table on the covered terrace. Many of my guests have had an intake of breath when they saw one there.
I think maybe it's the out-of the ordinary little features that a guest wouldn't just find anywhere that would make a impression, even quite simple things. maybe that's why they make no comment on the nice big bouquets that hosts here have said they left- a bouquet of flowers, while a lovely touch, isn't anything really unique.
As far as the kids go, I guess that's just a decision you're going to have to weigh- if you get a lot of family bookings, it seems a shame to disallow children, on the other hand, if you're going to allow young ones, you certainly can't have anything breakable around that is precious to you.
Some parents just let their kids run wild and don't supervise them. But I raised 3 daughters and I can tell you that they never broke any more things than an adult might. However, if I was staying somewhere with them, the first thing I would do is put anything that might be attractive to them and breakable out of their reach.
When I was abut 5 years old, my mother gave me a little tea set she'd had as a child and was saving for me. She made a big production out of presenting me with it and of course I loved it. But I managed to break one piece the first day I was playing with it. She got really upset, and even at that young age, I remember thinking "Why would she give me something so fragile if she was going to get upset if I accidentally broke it?"
