Did it in an inflatable Intex Explorer K2 in early September with no issues. I'd definitely carry a patch kit and pump always.
The morning crossing of Pitt Lake was very easy but coming back on a Sunday afternoon with some wind and fast boaters made it a little more interesting.
*Edit - Watch the tides as well. We were able to paddle up during high tide. On our way back during a lower tide we had to get out and walk through some very shallow sections of Widgeon Creek.
