I don't think I paid exorbitantly for anything in Alsace. I was there in May (so likely much cheaper lodging than July) and never paid much over 50 euro for a room. Meals were average price. Breakfast depends on what you have - I'd guess under five euros for a coffee and pastry up to a little over ten for a bigger breakfast. Lunch for me is usually a sandwich from a bakery, deli or small grocery store and a soda, probably just over 5 euros. Plan for ten if you want more than that or 15-20 if you want to try the fixed price menu at a cafe. For dinner, I looked for fixed price menus posted in front of restaurants. I probably spent from a low of 20 to a high of 30, including everything, each time. If you want wine, check the grocery store. Gewurztraminer is the best wine there (IMHO) and a nice bottle can be had in the 6 euro range (ask for a recommendation). The white wines there are typically drier than what you find here in the U.S.
My only highlight visit was the Castle Haut Koenigsbourg. I can't remember the price, maybe ten euros or a little more? There is a "Monkey Mountain" near the castle but I skipped it because I've seen the Barbary apes at Gibraltar. I missed the Unterlinden museum I wanted to see in Colmar. I planned Tuesday, thinking it would be closed on Monday, but it was closed. I could have gone on Monday but didn't think of it until Tuesday. Not the first, or last, bonehead error I've made in my travels.
