We rode Space, Star Tours, Matterhorn and a couple of fantasyland rides during our MM end of February, it was a Saturday so it was at 7AM which should be what you experience during your visit. We were first at the gate though, which helps - if you are quite a ways back it can add some time getting to those first rides you want so whatever you do make sure you are there at least a half an hour or maybe even earlier before the early entry. I am sure security lines will likely be even busier then so make sure you have time considered for that. Space will show a return time of 10 minutes right as MM opens and will likely grow to at least 30 minutes plus by the end of MM.
Pinocchio and Snow White are very low lines almost all the time, it's normally Peter Pan, Alice, Toad and Dumbo that have any sort of line in Fantasyland.
The best tip I can offer is to use fast passes to their fullest potential. That means getting one as soon as the park opens, then make sure you always have one in your hand the rest of the day, unless of course they have all run out. To do this you want to pull a fast pass as soon as the park opens (regular park opening, no fast passes are distributed during EMH orr MM). Then pull your next fast pass and so on as soon as you are able - it will be written on your fast pass when you are able to pull your next.
For example: Pull a FP for Space at regular park opening - you will likely have a return time of less than two hours, once that window opens, say 9:30 is your return time, then pull another Fast Pass before your ride Space since you will have a full hour return window, don't wait until after you ride it to then go pull one because you want the clock to begin ticking on that next fast pass while you are riding using your current one. If you pull a return time which is greater than 2 hours then make sure you pull your next one right at the two hour mark. Keep track of fast passes that are not connected - the two park systems are not connected, so you can pull a FP for Space and someone in your group could hop over to DCA and pull FPs for RSR, this takes far less time than you would think to do, we did it a few times. World of Color and Buzz fast passes are not connected to the system so if you are getting Star Tours FPs then pull Buzz too, (they are the two fast pass machines to the far left - looking out into the park from the fast pass machines). That and show up EARLY!!
Have fun!
