We will arrive in Barcelona mid-afternoon on a Thursday and then have 5 full days in Barcelona from Friday to Tuesday, departing on Wednesday.
Our plan is to visit Parc Guell , Hospital de Sant Pau (this one - http://www.santpaubarcelona.org/en ) and Sagrada Familia on one of our days.
I’m considering visiting these sites on the Sunday. Hospital de San Pau is only open until mid afternoon on Sunday so we’d visit Park Guell first thing in the morning, then Hospital San Pau and then after a lunch break visit Sagrada Familia in the afternoon. Is Sunday a good day for this or will these sites be more crowded on the weekend? I'm leaning towards the Sunday because some of the other things we'd like would be better ondays other than Sunday, while these sites all have good times on the Sunday. We could visit these sites though on almost any other day of our visit (Sat, Mon, or Tue) if that might be a little better.
