Into vs. In to
Let's clarify the "into" versus "in to" debate.
They're often confused, but "into" indicates movement (Lindsay walked into the office) while "in to" is used in lots of situations because the individual words "to" and "in" are frequently used in other parts of a sentence. For example, "to" is often used with infinitive verbs (e.g. "to drive"). Or "in" can be used as part of a verb (e.g. "call in to a meeting").
So if you're trying to decide which to use, first figure out if the words "in" or "to" actually modify other words in the sentence. If they don't, then ask yourself if it's indicating some sort of movement -- if it does, you're good to use "into."
