If you are playing at a table with multiple people who won't fold to any preflop raise, would it be optimal to limp to the flop and decide how I'm going to play the hand from there?

As I was playing AA in a four way pot at a six max table, I realized that rockets are huge favorites in a heads up pot, but not so much 4 way.

Also, would it hurt me as a player if I just deposited a few hundred dollars and played at a higher stake? Right now I'm planning on playing .10/.20 until I can consistently beat it, but eh, I've already seen this question answered a hundred times.
