Firstly, I would build a closed in pen where they can go for many reasons.
I feel that they are not on equal ground and you may also not be taking them at a time that they feel that they want to go, rather, doing a routine, 1 after the other, after the other.
Are your other two dogs older than Bacardi? And, had one of them previously urinated in your bedroom even if it was a couple of years or more ago? It sounds as if Bacardi purely wants to mark his territory, you..as the favoured dog which again makes me think they are not on equal ground.
If a previous dog had urinated in your bedroom no matter how long ago and no matter how hard you tried to clean it up, Bacardi still may smell it and is taking over as the dog...
Another thing to consider is UTI. If a dog frequently needs to pee, you need to take him/her to the vet with a Urine sample, to test for UTI's, they can easily be treated with antibiotics for 10 days but they can cause worse problems if left un-attended. I would make this your first call.
I have laminate floors, and have tried bleach, white vinegar, laminate cleaners, ammonia, and even store bought pet odor neutralizers, but to no avail
Speak to your vet also regarding the appropriate cleaner to get rid of odors Ammonia which is also in bleach mimicks urine, so you are actually drawing them to wee in the same spot.
When you take Jenny out for a poop, do you take her to the exact same spot each time? Generally this helps, it appears that she has found her own spot/s inside, therefore, if you concentrate on (1) spot outside and take her out more frequently being that she is only 1 years of age this may help further.
You should also leave a small spot and not totally clean it up (outside) so that she can smell it and know it's her spot.
If you catch her inside, don't tell her off, try to get her caught in the middle of her business and take her back outside to the exact same spot... She will understand that is her spot and she should stop pooping in the house.
When dogs are stressed about their territory their behaviour can also change, they will do things you don't like to try to claim that territory.
My honest suggestion would be to find a builder that can build something outside in your yard that has 4 entrances 1 for each dog, so they have their own space, territory and to try to make them all equal inside the home, not favouring one to the other...
Dogs offer un-conditional love. They are priceless. If they feel they are not loved as much as another animal, they will also start mis-behaving, to gain the attention.
There is a lot to think about there.
But I would start with a Vet, for UTI for bacardi, and speak to them about the appropriate cleaner and throw away the products you have been using.
I would then totally clean the bedroom, talk to someone about making an enclosed area for the dogs and then try to treat them all equally.
Think about it, if you have an enclosed area that each area belongs to one, and is big enough PLUS you let them all muck around together, chace the ducks etc, they can all go out at the same time, feel equal and you don't have to go one at a a time every day of your life, morning, noon and night which surely such a routine must get you down as well.
That's my suggestions.
