The ARW wasn't solely about taxes or solely about representation... it's more a matter of self rule. The main cause of the ARW was not a single event, but a long history of benign neglect by the home government. Essentially, London didn't bother the colonists much for a long time, other than foisting a series of hapless governors on them who also didn't bother the colonists much. There were already taxes and customs duties in place, but neither the governors nor London bothered much to make sure they were actually gathered or accounted for (a couple of the Founding Fathers were actually royal tax collectors or customs officials who proved unable to account for the funds they were supposed to have collected). Smuggling in the colonies was rampant, mainly to avoid customs. The colonies pretty much ran their own affairs without deferring to London. Essentially, the colonies were practically independent before the ARW, in their own minds. A long history of going west, expanding the frontier, and being self reliant (especially in the face of French and Indian raiders) had made the colonists rather independent in spirit already. The ARW wasn't all that much of a surprise to a lot of people; several in England and France predicted it (most famously, Count Vergennes). What prompted the ARW more than anything was the idea that Britain would suddenly be actually running the colonies directly, and collecting all those taxes and customs that they'd been avoiding for so long.
So, to get back to the POD, it would take more than a visit by the king to avoid the ARW; you'd have to go back to the very beginnings of the colonies and have the home government run things more directly from the start...
