We have the living room gated, and I can leave M in this child-proofed room for a few minutes of unsupervised time, especially if her 3 month old brother is with me or in the pack n play. I can leave her for an hour if I turn on Sesame Street, but I still check frequently, and I only do this if chores have become insurmountable and I really have to leave her alone. She can play by herself well, but I like to be in the same room because she tends to get bad ideas that remind us that nothing is really completely childproofed.
With potty training, we are thinking about taking down the gate. I can't chase her around the house because I am often nursing or otherwise busy with her brother, and plus I just don't want to run through the halls visiting every room 1000x each day. With the gate down, she would have access to the bathroom, dining room, kitchen, our bedroom, and her bedroom. I am working now on childproofing these rooms more, but I am worried about letting her just play in the kitchen or whatever by herself. Right now she gets only about 30 seconds alone in any other room or on our enclosed deck. I suspect we are conservative compared to other families, but M just finds trouble. On the other hand, maybe she would be able to be more trustworthy if I gave her a bit of independence.
Re: how long is your Feb toddler unsupervised?
DD and DS have open access to the living room, kitchen, and dining room. That being said, most of the kitchen cabinets have child locks on them (except for the one with the pots and pans they love to play with), and there is a baby gate that prevents them from getting to the kitchen garbage can and the downstairs bathroom (I wouldn't trust them for a second with either!).
I am pretty comfortable having the kids in a different room than me when we're downstairs, although if it starts to get quiet for too long, I always go check on what they're doing. The stairs are gated and they're never allowed to go up or down them without an adult. They also never really spend any time upstairs in any room alone.
We also have child-proof handles on the doorknob of the front door and the basement stairs.
I can see how potty-training presents a supervision/child-proofing dilemma. How critical is it to potty train M right now? I wonder if waiting a few months would give her a little more maturity and impulse control so you could feel more comfortable with the lower level of supervision. Either that or could you put a child-proof handle on the outside of the bathroom doorknob or an easy open walk-through gate across the door? You'd have to open it for her every time she needs to go, but that would prevent a lot of bathroom mischief. Although it might also result in more accidents.

It might be confusing to have the potty in the living room. You want her to associate peeing/pooping with the bathroom only, otherwise you could potentially have issues later on with her going to the bathroom in other places in your home.
If the 3 day weekend is the biggest motivation for potty training right now, it might be worthwhile to wait a bit. Even once she gets the idea of how to use the potty, she's still going to need a LOT of supervision and assistance in there for a while. Waiting until both kids are a little older might make life easier.

We give him pretty full reign of the house. We didn't while the tree was in the house, he would not leave it alone.
We don't have a gate at the stairs now because we finished the basement. We are always on the same level of the house, if he goes downstairs I do too. If he goes up I'm up too. We don't have cupboards locked, there's nothing dangerous in the ones he can get at so I don't worry. He had snacks accessible to him in the kitchen and pantry at all times and comes to tell me whenever he takes something.
