The thing that made the biggest difference for us was having a potty nearby ALL THE TIME. We had two in the house, upstairs and down, plus a My Carry Potty in the car that went everywhere with us for quite a while. We were "those people" with a potty on the median or behind a tree at the park.
You don't want to focus on holding it at this stage, you want to focus on "pee and poop go in the potty." Getting her to a potty ASAP is the goal.
I honestly feel that going cold turkey is the best way. It was three days of hell, but she was 100% by day six and has had only the normal 1-day regressions or distracted accidents since then.
I like the book Time to Pee by Mo Willems - DD was already PLed when we read it, but it really reinforced the potty nicely.
