I thought the Prince of Asturias still had a wide approval amongst the Spaniards, alike the Queen and Doņa Elena.
Doņa Letizia's popularity seems to depend on who you ask it. Also they have shown nice glitter, be it not in Spain.
There are still State- or Official Visits to Spain, there is still a lot of ceremonial around (the Crown Prince of Japan this week was received with all honours) but only for visiting royal heads of state the jewelry cassette goes wide open, so it seems.
