An easy solution might be just to stay at the Crowne Plaza in Terminal 3. Only takes a few minutes to get across to T1 in the morning
Or take a slightly later flight (or even similarly timed flight) on whichever airline and stay in town, given OP is coming into town anyway. It takes 5-10 mins or so to get from the Crowne Plaza to T1 or T2 (including walking time + waiting time for skytrain + skytrain time) - it takes 20 mins via taxi. Not a lot of difference.
