Only ways to speed up the SLAM are:
1) brush more often like as often as you want, no limit - walls and floor - vac once a day
2) test FC using 10mL sample size & instructions (skip CC) more often and bring FC back up to shock more often. You can do it every 30 minutes until it doesn't change, then every 60 minutes until it doesn't change, then every 90 mins or 2 hrs, etc. If you have to leave for work in the AM, while not official TFP practice, and certainly not financially efficient, I have, once or twice, added an extra 4ppm above shock figuring the algae and sun would have it back under shock way before it would hurt my plaster (but i do not know how tolerant fiberglass is of FC above shock)
3) when you're home and able to watch the pool, add polyfill or socks to the skimmer basket

read this so you know about it and are prepared if we tell you it needs to be done, hopefully not

Double check - still filtering 24/7 and I would NOT add anything but bleach/chlorine and fill water as needed until my water got to cloudy white blue (then we can discuss the add DE or cellulose fiber options I mentioned in #5

I can't tell you if it will be swim ready by your party, but I can tell you that the more often you #1 and #2 - the better your chances
