Our Best of Scotland Tour starts on a Wednesday at 4PM. We'd like to take advantage of the recommendations RS lists in the guidebook (for spots the tour won't cover). Our choices are:
National Portrait Gallery
Holyrood House (Queen's Gallery only--as castle is closed for a private event)
Royal Yacht Britannia
Would love to hear everyone's thoughts on what is doable/not doable (time constraint of 4PM) and/or not to miss.
