My DW and I are talking about "what ifs" -- What if DD2 DOES like Flounders and we end up with a couple of moments of adult time? And we'll keep it clean here!

We know that DD7 is going to be fine at OC - she is VERY social and talks about "when I make a friend on the first day, can we make plans to be in the club together - to go to the Goofy sleepover," etc.
But if we get lucky - DD2 watches the video and when Flounders comes up she says "I wanna go there" so our fingers are crossed.... But if we get lucky, here is our plan:
1. We'll book 3 or 4 two-hour windows just in case. The first one we will use to just hang out. Swim in the adult pool, have a drink at the Cove..walk around the ship..explore everything we can and that we might not be able to do with both kids with us. IF we dont' get the call to come and get her, then we'll go onto the second two hour window another day.
2. During that one, we will pre-book something in the spa - couple's massage if we can get it in the private cabana. I'm assuming there is a cancellation policy - one that allows us to cancel with some kind of notice..so if we do the first Flounders and it doesn't work, we can then cancel, correct?
3. If that works, then we will play the rest by ear. Maybe get some additional time together that would be such a luxury.
We're not going to book Palo at all only because we go out to a lot of nice dinners - both here and when we travel..both with and without kids (our DD7 is a GREAT restaurant kid..always has been). So I'd rather not "waste" our precious free time getting dolled up for dinner and sitting through a long meal. I'd rather hit one of the nightclubs if we can do a nighttime thing.
Anyway, what do all of you think?
