Duckling, I'd well over 100 dives, just off of San Pedro before any hohum factor ever kicked in. Even after all those dives, some sites and some dives are still just great!! Just ask those that have had even more dives there than myself.
And every day and every dive can offer up something different or splendid. You just never know. Will it be a turtle trying to kiss you? A free swimming moray? Nurse sharks circling about? Spotted eagle rays at flight? Or smaller finds, like Pederson Cleaning Shrimp and dancing juvenile spotted drums. Even without all the fish, the underwater scenery can be captivating.
Slow down and smell the underwater roses, as it were.
If you love diving as you say you do, I'd be quite surprised if you become bored with only one week of diving off of San Pedro.
