lolol. Same here…how can one improve on perfection 
Just kidding!
@rolf - I have never used a suggestion box but I kind of am aware of what could use improvement and certain things just have to wait for now. Such as setting up a convenient place to plug in electronics, etc.
I wouldn’t use a box only because my partner would read the suggestions and then think he should provide extras like hot tub, etc. and I already know I won’t be able to get a higher rate for added amenities.
