Full discloure, I'm a big CL fan and especially a Poly CL fan.
Since price is a push, it really just depends on how much value you place on being able to see MK directly from your room. I guess only you can answer that question.
But as PP notes, the CL lounge has a wonderful view of the MK - so while your room will have a garden / Oasis Pool view, you always have the lounge there to get your TPV fix. I agree with
@anomamatt in that it's not quite the same as having the view from your own room, but it's a close second.
The main word that always comes to mind with Poly CL for us is "convenience" - the location of the Hawaii longhouse is just so convenient for lots of things - from pool time, to transportation, to popping out to the beach for fireworks, etc. The CL offerings are also very convenient - I don't have to go to Cap't Cooks for something small like a cup of coffee. The breakfast offerings in particular are an adequate substitute for having to eat breakfast somewhere else for most folks.
Even the evening apps - historically Poly CL's weak spot - have been much improved over the last few months.
I'd say if you've been to Poly several times and don't mind giving up the TPV room, I'd say go for it, if only to try something different and experience the resort in a new way./QUOTE]
