The first thing I do after after a flight is check the oil level. It only takes about 3-4 revolutions to hear the "burp" and then check the oil level.

The next time I go to fly for reasons I am not clear about the oil level is the same without the need to "burp" the engine. After checking the oil level should I rotate the prop anyway to make sure there is not "hydraulic" lock ? Is that even possible in a Rotax engine? Does rotating the prop help lubricate the engine before the next start?

Here is some fairly recent info.

I usually rotate the prop a little before start just to make sure everything sounds and feels right.

The only purpose of burping the engine is to make sure all the oil is in the reservoir before you check the level.
