Thank you for the information! I have been trying to find more information about new years eve on the Poly but there's not a lot. Does the viewing area on the beach fill up quickly or could I arrive at 11:00 pm and be fine?
Happy to help. On 12/31 historically they fence off the main beach viewing area and tightly control access for just Poly guests so you can be very flexible in your plans, generally speaking. There will be recreation activities all evening - usually a DJ on the beach, characters, etc. The pool and pool bar stays open late and sometimes they have had a beer/wine station set up on the beach. Lots of hats and noise makers (yay??).
As you get later in the evening people do start staking out spots in the “prime” viewing area on the beach - people brings towels/blankets, claim their spot, etc. If you’re content to not see the castle directly there will be plenty of space on the beach right up until show time so you can kind of wing it. There’s an island that blocks the castle view from part of the main beach area but not the fireworks and it’s a plenty good show even if you’re in that area - but a lot of people tend to congregate in the window where you can see the castle (some of which will be an additional reserved area for CL guests). They use additional launch points for the 11:50 show, one of which is the island right in the middle of the lagoon. So it makes for a very good show and the viewing is great.
I will caveat that exact setups and procedures tend to change a bit year to year. It’s like each year brings a new manager/new CMs and whoever is in charge comes up with a new plan. This past year’s setup was the the best in years and it felt very controlled. Poly tends to start crawling with guests and non guests as the evening goes on, which makes the usual beach setup a very valuable amenity, IMHO.
I love NYE at Poly but I’d also suggest it calls for a bit of a “roll with it” attitude. Disney tries to staff up for the evening but it’s also an evening many regular CMs have off, so the people working the bars, resort, check in desk, etc can sometimes be new or filling in from other places and may be a little slow. Plus there are just lost of people around so lines for Dole Whips, Trader Sams, Tambu, etc can really ebb and flow. But it’s the best resort for NYE as far as location, in my humble opinion, and I love the vibe.
Sorry for the long ramble, just happens to be something I have a lot of experience with.
