I've seen the confirmation that the resort fee will not be applied to award stays. What about points+cash?

Points + Cash is a point-supplemented paid rate, not an "award stay".

A definite yes to resort fee on that one
But not if booked before the announcement or stay is taken before the start date of the fee

So the people that book an award stay will be able to partake in all of the activities covered under the fee, but those that book a paid stay before the compulsory resort fee rule takes affect will have to either pay the fee or pay for the activities individually?

To my understanding yes
Its always worked that way with the waived resort fees at other Hyatt properties over the years when booked on award

After Resort Fee takes effect, other than for those with reservations made prior to announcement, it would seem that there would be no need for "individual activity" charges, if activity is listed under Resort Fee amenities.
For those taking advantage of listed activities, if in fact all activities are included at no additional charge, this is a good deal, as far as Resort Fees goes.
What remains to be seen: Are all the listed activities, such as bikes, boogie boards, kayaks, snorkel equipment, etc free, or are they only being made available for an additional rental charge? Why are they listed as "rentals"?
I guess we will have to wait until June to find out.

i am going to assume that the resort fee is prorated for p&c 50/50... similar to how they do it for other Hyatts that have a resort fee

Parking Situation
 

Anyone know whether they take inventory at night? Thanks

With Hyatt it's either charged or not. Diamonds sometimes get a discount, but it's not prorated.

Yes, you can use valet for free (minus tip) during the day and if it stays over night that is when they take inventory to charge. There are a few places you can park and walk back to the hotel for free (~10-13 mins).

Does the Andaz Maui offer rooms using Hyatt Gold Passport points? Every date I try says rate not available?

Maui and cheap. Wrong place to visit...

Tens of thousands of Hawaiians manage to live on Maui without spending excessive sums on resort meals. There are absolutely bargains to be had.

Although if you stay at a pricey resort like the Andaz, it's difficult to avoid getting gouged.

So not true. If one has a car (and Maui is an island that begs to be checked out) there are so many cheap local places to eat.

In fact, Maui is a very cheap vacation (say compared to NYC, Disney, skiing...) if one does VRBO, discount car rental, Costco, local restaurants and shopping, and free day activities like beaches and shore snorkeling/diving and hiking.

And, back to the Andaz, if one uses points (not C&P) and local restaurants, it can be a very cheap trip (compared to skiing, big city trips, Disney, etc.).
