I had such a struggle with my toddler getting her to take a break from her toys and fun to take time to use the potty... The only thing that worked for me was "I'm going to get there first!" and running to the potty fast.
You might find that she really doesn't have to go as often as she did when she first learned... my nearly three-year-old only uses the potty three times a day now (or sometimes only twice a day!).
I do find that I have to limit juice and fruit to only two small servings of fruit or juice per day, especially if we are doing something REALLY fun that she won't want to take a break from, or else she is more likely to have accidents.
If she's bored, getting a new special potty might make it more interesting for a while. Ikea has cheap ones with lots of fun colors. Take it away and hide it every few days and bring it back out from time to time to keep potty time more interesting!
If she's in a big girl bed, you can just put a potty in her room if she's insisting that she has to go potty before a nap or bed. Tell her if she uses the potty, you'll come help her clean it up, but otherwise, she'll have to go back to bed on her own.
I'd say if you can play outside more while it's nice out, leaving a potty outside for her to use if she wants, you'll at least save yourself a few clean-ups!
