(I'll post a Spain Activity Trip Report later this week)
I realize that are numerous factors that will change what others spend on a vacation compared to our trip. But, just for a comparison of our trips over the past 4 years, here's the results. I'm an engineer, so every expense was tracked (even our daily gelato!). Even though I track expenses, it's just for my trending & planning; we spend what we want during each trip and don't turn down activities, selection of hotels or restaurant choices because of it.
I removed the airline flight costs and divided expenses by number of days for a true comparison. Our transportation is trains and the occasional bus. We stay in the center of towns & love to walk and take local transportation. We are a couple, so hotel costs are divided by two people:
2017: Spain trip: $112/pp/day. One factor for the lower cost was that we ate late breakfasts, so skipped several lunches. Also, hotels were cheaper for rooms comparable to other trips.
2016: Italy/France trip: $146/pp/day. Splurged on Italian meals & expenses at Paris.
2015: Germany/Austria: $145/pp/day. Splurged on some extra special hotels, i.e. Cortisen am See Hotel at St. Wolfgang, Hotel Am Stephansplatz at Vienna.
2014: Switzerland/Italy trip: $163/pp/day. The Swiss transportation & hotel costs affected this price, along with lots of Italian food!
