1) I will be visiting Scotland several times in the next few months.
I will visit Scotland several times in the next few months.
They are interchangeable in some contexts but generally I think of 1) as your informing someone else of your intention to visit Scotland and 2) could be the same meaning or also could just be your internal thoughts/decision. If you were considering whether to visit Scotland or not, and decide yes, you'd think 2) not 1).
