you mean in between parts of the PS? ours was all at the GF (francks was down for rehab, our reception is at the whitehall room), but it was a several hour all-in-one affair. i think our times were listed as different blocks, but there wasn't an oppurtunity to do stuff "in between"? i'm sure you probably aren't all car pooling with your planner to the tasting site, but i would imagine that unless by "check out the xmas decor" you mean "walk through the lobby really quick" i would think you wouldn't have time to drive over, park, go look and then get over to the boardwalk and park etc.. without taking a bit of time. i'm sure others with your logistics will chime in!
good luck!
