I might have lost track slightly. As far as I can see, you already have the design ready, but the tabs are not working? It seems like all the tabs content is outside any tabs container. Furthermore, I see 3x tabs, and 6x blocks of content, and it's unclear what blocks go inside which tabs ... It looks like there will be 3x blocks inside "couple packages", 1x block inside "premium packages" and 2x blocks inside "luxury packages", correct? In which case, you would need to create an appropriate inner grid/columns for each content section inside the tabs, like you already did for 3x "couple packages".
So with the above in mind, are you looking for a basic Javascript solution that will allow the tabs to work then? Also, because it seems you have diverged from the design of the original screenshot, which seems to have been based on the existing X3 tabs content plugin?
