Help me combine these two projects into one Blockbuster project.

Question

I would like to combine these two projects into one mega project. Whilst the program (Holiday resort project) is loading, I'd like the progressbar to show the progress of the loading in percentages and when it's done loading (thus reached 100%), output the holiday resort project. Viewers should not see the pictures loading and the only time they should wait is when the progressbar is loading. Codes of the said projects are provided below.
