Lots of questions! We'll try and give you a hand.

16 oz. of stabilizer was a good initial dose for this size pool. It should take your cya to around 30ppm. How did you add it? Do NOT add more at this time. It takes awhile to show up when you test for it. Until it begins to start showing up on a test, it is hard to keep chlorine in the pool, as you have found out! For the first week or two, it is necessary to test and add chlorine morning and evening and sometimes even in the middle of the day. After your cya shows up, you'll be able to go to evening testing and adding chlorine only once a day.

The cloudy water could be from one of a couple of things. What kind of granular chlorine have you been using -- cal-hypo or dichlor? Both can cause cloudy water at times. If you are using cal-hypo, I would suggest that you stop. Your calcium hardness reading is already high and a vinyl pool doesn't need calcium. We recommend just using plain bleach for your source of chlorine. It will not cloud you water. Your cloudy water could also be from an algae bloom trying to start from not having a consistent chlorine reading in there. Or it could be from high TA and high CH.

Leaving tomorrow for Father's Day complicates things a little but being with family on a holiday is more important than a pool. I would suggest just adding about a gallon of 6% plain bleach before you leave. You can also leave a couple of the tabs in the pool while you are gone. Covering it will slow the chlorine loss but you may still come back to a cloudy or green pool. But, if that is the case, we will help you get it cleared up next week.

What kind of filter do you have? You also need a good testkit. We recommend the Taylor K-2006 which can be found at this link for a pretty good price.

If you can, maybe go ahead and order one so it will hopefully arrive next week.

Hope this helps some. Repost if you have any other questions and somebody here will try and help.
