Then I guess Disney had better get rid of all bees. Last time I got stung by a bee, my skinny leg blew up like a football. It was Benadryl 24/7 for days. (I don't remember those days, but I'm aware they existed.) NO BEES at Disney World, because my necessity is not having severe allergic reactions.
Since some people apparently can't see beyond their own circumstances, maybe an anecdote will help (although I doubt it, since they've been repeatedly, stubbornly ignored on this thread.)
I don't *need* to bring my dog everywhere. Most of my WDW trips are 2 to 3 nights. We have a local sitter who will come to the house 3 times a day. The dog stays in her own home, and we wonder if that isn't better than being in a kennel.
The sitter is great overall, but not always perfect. She can fall asleep and let the dog stay longer than 8 hours overnight before she goes in the morning. (And yes, I am checking on my home alarm app while we are at the parks.)
Sometimes when we return home, we find out puppy has gotten sick. She's also very happy to see us for the first 10 minutes, and then as standoffish as a cat for the next day.
Some other times, we bring her with us to Orlando. In that case, to date, we couldn't stay on property. We'd stay at a Red Roof or a La Quinta. WE NEVER ONCE left her in the room. Not for 10 minutes. One of us would go for food, or we would order in. We would do no Disney the first night so she could settle in. When we did go to the parks during the day, we took her to Best Friends Pet Care. If we were going to be gone most of the day (we're getting older and that doesn't happen as often) we will go visit her once or twice during the day (see my trip reports.)
While I may feel bad leaving her in the kennel during the day, this is the fact: when we turn onto Bonnet Creek Parkway, she knows where we are and gets all excited. She knows she will see other dogs. She knows we will play with her out back for a good 30 minutes to tire her out before she goes into her indoor/outdoor space (bigger than a cage or crate.) Side note: it's better to tire her out first by playing outside, because she'll be more tired than anxious.
Until the recent hurricane episode, we never left her overnight. We'd pick her up at night, take her back to the room with us, and have a "normal" night's sleep. Sometimes we'd break up her day at BFPC with an ice cream treat; sometimes with a bath.
She never got sick under those circumstances.
So, while you can see positives and negatives for both situations, my interpretation is that she is less stressed and anxious when her daytimes at boarding are broken up by nighttimes with her family all in the same room.
Now, she may be different from other dogs, she had some separation anxiety when we first adopted her (at 7 months) because the previous family that adopted her thought she was too much trouble and brought her back. Once she got comfortable with us (about 7 years ago) that separation anxiety greatly decreased, but it's in the back of my mind, as in, "I hope she doesn't think we're never coming back for her."
She is also a bit unusual in that she rarely - and I mean rarely - ever barks in day to day life. Notable exceptions: cats, and doorbells. Other than that, there can be other dogs barking in the yard next door, and she does not bark.
So I, as a dog owner, feel perfectly responsible to her, and to other guests, by bringing her to Port Orleans at night and taking her to BFPC during the day. I dare anyone to contradict that with something real.
Nor are you sleeping in those bedsheets the next night. They get changed, remember?
Moreover, they are having sex in those bedsheets. (Sloppily, after Food & Wine Around The World) and their children wipe their snotty noses on those bed sheets (don't tell me it doesn't happen - because it can...see how silly that argument sounds?)
