I'm going to Canyon Villas in Phoenix in June. Would love to hear about your experience.
We were just there for a week in March. Weather was in the high 70s, low 80s in the daytime, 50s at night - we slept with the window open, listening to the waterfall, and had perfect *baseball* weather for all the games we saw. However - you are going to be there when it is HOT HOT HOT - not as bad as August, but I think you need to look over the historical temperatures, and the long-term forecasts. We were just glad to get away from all the snow here in upstate NY.
We basically used the resort sleep and eat breakfast - we were OUT every day. Had friends from Canada who winter there - and they all LEAVE in April, because it gets nicer in Alberta, worse in AZ. It took us a couple of days to even find what we wanted in the huge mall down the road - next trip back ( and yes, there WILL be a next trip - we liked it there!) will be better. LOVED the Musical Instrument Museum (we are professional classical musicians, and retired music teachers) - but you must plan your visit; do the things you like downstairs, but once you head upstairs, start with the American and European instruments - HUGE HUGE collections - and if you have any energy left over, you then can peruse the huge collections of instruments from many world cultures (unless of course, you have specific reason to start THERE first.) Our Canadian friends took us to this place that, upon hearing OF it , made us roll our eyes (not that we are snobs - but everybody who knows pro musicians thinks they know of someplace that will impress us - not quite . . .) but we had SO MUCH FUN - and cheap . . They took us to Organ Stop Pizza in Mesa - the size of a German beer hall, but pizza and weak beer /soda - and the world's largest Wurlitzer pipe organ, with orchestrion (additional added percussion, trumpets, etc.) and REALLY fine players. Before you go - learn ALL the words, and practice the Star Spangled Banner AND O Canada - you will need to known them - depending who is seated at your table.

Since we were there mainly to watch baseball, that took up the best part of three or four days. You will want indoor, cooler things to do. If you go EARLY or LATE, when the temperature in endurable, you can go to the Desert Botanical Gardens - again, wear good walking shoes. We also went to Taliesin West - interesting, but we no not need to see it on the next trip.
We never used the pool when at CV - too many other things to do. Next time, we will see if we can stay near the quiet pool - too small for any exercise swimming, but good for just a cooling dip.
So have a great time - look for COOL things to do in the heat!
