To address the OP's question -- multiclassing is a fairly modular component to the game system. You can not include the option and it won't screw up balance mechanics.
Same could be true of any race or such.
But, yeah, if everyone is new to the game, it may just overly complicate it for that player.
When your second campaign rolls around, at least consider reopening it as an option if someone expresses interest -- they might like the variety (but seeing as how they are new right now _everything_ is new and shiny, so that won't be an issue for their first experience).
