the wife and I stopped by around noon to rent SUP for an hour. we thought it would be just an easy walk up, but come to find out, this thing is really popular! we were put on a wait list and came back about an hour later to begin our SUP'ing.
the girl at the reservation was kind and sweet and was actually apologetic for the long wait. we walked over to the dock and the guy there gave us a quick lesson for the SUP and we were off. it's not hard, well...not on Tempe Town Lake anyway.
the rentals were 20 bucks/hour which included the paddle. don't ding or lose the board or paddle...it's expensive to replace! the boards are decent, though not anything wicked cool, but they were fun to just enjoy a day out on the lake.
you don't really need shoes or flip flops. they will let you store any gear you brought in their office, but really you just need a sunhat, sunglasses, and swimsuit...
return was just as easy as renting. if you have to wait, no biggie....mill ave is 5 minute walk away!
