You can set intention to notice the little wakings during the night, and if it's important enough to you and you try enough, you will notice them, giving you an opportunity to do WBTB without the problem of the alarm.
WBTB and sleep and dreaming patterns are highly personal -- lucid dreaming is a journey about discovering the balance between relaxation and awareness, the experiences of falling asleep and dreaming. Try many different time and durations. I personally aim towards micro-WBTBs (not even getting out of bed, just re-setting intention, and doing a meditation while falling back asleep).
