To keep it simple, lets just take Sacrament meetings. I think it's fair to say (for believing LDS) that the Spirit will always be present in a Sacrament meeting. He has been invited, a sacred ordinance is taking place, absolutely He would be there.

This does not mean that everybody present will feel it. I think there are 3 reasons this could be the case, in no particular order.

1. Lack or worthiness. Although I think this is MUCH less prevalent than some would have you believe.

2. Lack of preparedness. If you're not receptive to it (stressed out distracted, surfing the net, etc.) your'e not going to feel it.

3. Lack of need. I think spiritual manifestations occur on an "as needed" basis. Perhaps you don't need strenghtening right now. You're on the right course, doing the right things, and/or it's just a time when He wants you to figure it out on your own.
