If you love BC, I would buy there enough for a 2B+10% and enjoy the heck out of it for the next 18 years. We only have two kids, but once they become teenagers, the 1B won’t be cutting it when we’re all on different sleep schedules and I want the living room for quiet coffee/wine/reading in peace.
We really like BW, but no dedicated 2B is a bummer. Cooking in the room is handy for the wallet and waistband, for sure. We have a standing grocery order that we tweak; milk, creamers, sandwich fixings, salad kits, rotisserie chicken, popsicles, eggs, cheese and crackers, popcorn, and we always throw a couple boxes of Mac and cheese in for kid

. Since you’re driving, you could always bring a lasagna or casserole, even just a large salad to peck on between meals. I would suggest soups/stews, but not in FL in June! LOL.
