I've currently been putting all the episodes from Travel Guides aired in 2021 as Season 4, but I wonder if I should have put the first four episodes into the "specials".

Thinking back, in January there were some ads for the show that mentioned "special" when talking about the four episodes with locations specifically in Australia, that were aired over the last week of January/first week of February.

Then they announced that the show was coming back around the end of April, which can be seen from the description of episode 5.

My question is, should the first four episodes be moved to a "specials" season?

I don't really have a preference either way, but I'm not entirely up to scratch on TMDb guidelines around this.
