Poly CL rooms are in the Hawaii longhouse, which is a well located longhouse (IMO). Views can vary depending on your room view category, but a third floor Poly TPV room is, in my opinion, among the best possible room views in all of WDW. Regardless of your actual room view category, the lounge has a fantastic castle view.
“Worth” is always so subjective and no right or wrong answer of course, but I’m personally a Poly CL fan. The convenience of breakfast and an occasional snack/beverage/beer/wine has value for us (family of four, kids currently 11 and 7, just for context). Just simple stuff like having a quick cup of coffee handy vs having to go to Captain Cook’s. CL offerings tend to ebb and flow in quality/quantity over time, but pre-COVID Poly’s food offerings were pretty strong and generally well-recieved. We’ll have to see what things are like when it reopens in Feb.
Financially the food math vs cost of a CL room won’t really work out for most, but it’s more about how much value you put on the small conveniences and other CL services, in my opinion.
I can find things I like/value in any resort or CL, but Poly CL has been our most frequent destination over the years. The resort, location, CL services, views, and overall Vacation Kingdom vibe provide the full package in what we seek in a WDW trip.
Just one person’s perspective - happy to answer any questions.
