That's a popular way to do it! But I think it may end up being the way to do it, at this rate. The restaurants used to be very popular in spite of the prices. We eat out as we don't want to cook (enough of that when we go camping!) and the quality of the restaurants is genuinely good (especially their gluten free provision). Whoever buys CP will need to adjust to a new reality though and go much further down the price scale for purchases within the park (one place that was always extremely busy was the Starbucks!)
