I don't really think anything makes it special per se. We ended up in the club level because we wanted a lagoon view room on the east side -- before we knew about the bungalows -- and the only way to get that was to go to Hawaii. We requested Tahiti, but it's gone now. Our previous two trips had been great -- the kids could go out on the beach at night, watch the fireworks and the boat parade and then come back in, and that's what we had hoped to replicate. We didn't know -- and weren't told -- of the extend of the destruction, or else I would have moved.
I'd stayed club before and was unimpressed, but you get into a "but this is what we're paying for" mentality that had us locked into the idea of club level this time.
But if you're asking me is there anything fundamentally special about club level in general, I don't think so. If you're asking about the Poly, for the time we were there, being club level was the worst place to be, and they knew it. The concierges were annoyed most of the time because people kept complaining about the same things day after day. Because beach access was limited, the lounge was over crowded and you had to stake out seats before the fireworks. And with the new round of construction at the quiet pool, things will be just as bad on the south as they were on the north.
You asked about the TTC path -- they reroute it to the parking lot, so there's a fenced off sidewalk that goes next to the large parking lot and the main Poly entrance street. They've got it fenced to prevent people from walking across the street, so it ends up being maybe 300 yards longer than it used to be -- not the end of the world, I know, but different.
