Yep, little blue dots will be along the center line of the hangar for ships and scattered around the edges for other things like ground vehicles and flair if you have any (decorations).
For ships you have various size classes, so size 1 to 2 ships, 3, 4, 5 etc. Some hangars don't have a class 5 spot as they are too small, so go into Revel and York as thats the biggest if you have somthing sizeable like a Starfarer.
Once you have spawned a ship, you can walk around inside it in total safety, so if you do have a Starfarer it's better to spawn it there and explore inside and learn were everything is, rather than spawning it on a Pad at Olisar in the PU and then spending 30 minutes trying to find the cockpit :)
