Hello! My husband and I are venturing to Scotland at the end of March. It's our third European trip.
For our last two trips we each packed a small 21" suitcase because much of those trips involved subways, trains, etc, and we wanted the ease of use of the small cases. However, for our Scotland trip we're only using a train once (between Glasgow and Edinburgh) and will have our own rental car for the entirety of the remaining two weeks we're there. Do you think it's still advisable to each have the small suitcase, or should we consider only having one medium sized suitcase? Does it matter?
