I think once you book something, it blocks out all conflicting excursions so you can't see them anymore. I have no excursions scheduled for Barcelona, and so when I check, I see lots of Barcelona excursions as being available.Ok, I went in and checked what is available for you and this is all I got:
Barcelona - Nothing
Cadiz - Flamenco in Puerto de Santa Maria (CD-08)
Gibraltar - Dolphin World (GB-07), Fortress Gibraltar (GB-06), Ocean Odyssey Sailing Center (GB-14), Panoramic Gibraltar & Afternoon Tea (GB-02), Rock Tour GB-04)
Tenerife - Nothing
Hope this helps you!
Can someone who has nothing scheduled in Cadiz check to see what is available? I have the Taste of Cadiz and Jerez scheduled and I am debating about cancelling so I can see if the Horse show comes available. However, I don't want to give it up if it is also full. If I can't get into the horse show, I'd like to do one of the other two that go to Jerez for the sherry tasting.
