Hey there PHLtoMCO!
I too have been fortunate enough to be able to stay at the C.L. at Poly more than once and I have to respectfully disagree with my friend BlueJasmine above me.
I made a whole YouTube video debating whether C.L. was worth it or not and overall, personally, I don't think it is worth the amount of money you'd pay for it. Here, let me put it to you this way ... if your vacation is all planned out and you are doing everything you want to do and still have money left over to pay for the upgrade to concierge then go for it ... but if you are sacrificing other things in order to get there then I would say no.
Listen, Club Level IS a nice perk and you definitely feel like your poop don't stink when you are the only ones who can access your building, and you get your own private lounge, and free sodas and snacks. I get that and when we stayed there I felt like that too!
However, think about it. You're getting the same room as everyone else, you can get, basically ... almost, the same view from other LongHouses, and even if you made a meal out of the little snacks ... which some people do ... I don't think it will even out to what you'd be paying for a meal if you weren't staying at C.L. and had to go out.
If you are looking for a really nice view at Poly you can either go with a M.K. view from the Tahiti building which is right next to Hawaii but not a C.L. building OR make a request ... and the cast member will tell you the standard "A request is just a request ... we will do our best to honor it but it is not a guarantee" line ... anyway, make a request for Samoa, Level 3 (so you have a balcony), facing the Volcano pool! I personally think the view is just as good as a Castle view ... good scenery, you can people watch if you like, and it's 100s less than a C.L. room!
Bottom line ... The only way I'd endorse a C.L. room is if you have the money WITHOUT having to sacrifice anything on your list!
JUST MY OPINION!
Take Care & Be Safe!!!
