So far it's been really easy leveling in LFD as Holy. Some nights are even instant-queue, with worst-case scenario a 3-4 minute queue.
95% of the time all I cast is PoM and Renew. On 90%+ of pulls I don't even have to drink afterwards, it's so mana efficient. Only time my mana dips is with a crazy pull or an undergeared tank where I have to spam some Flash Heals to keep him topped up. And when that happens, I send my shadowfiend out to regen some mana for me.
Circle of Healing, a staple of a raid-healing holy priest, is seldom used in 5-mans.
Main reason I'm holy and learning the holy healing style is because my guild needs a RAID healer, not a tank healer. All our main healers right now are tank healers. Thus the choice of Holy over Disc. Learn with what I'm going to use in a raid. :)
