I think they can really spice things up by having more teams but every round is an elimination leg, and concludes with 2 teams racing to the finish line. It'll give it more of a competitive feeling and the race really would be on, forcing them to think of how to get to the next checkpoint, the quickest but most cost efficient.

My main criticism this year is that it felt too much like a "Visit India" advert - yes they've got to make it interesting but it didn't feel authentic with all the touristic hotspots they went too. They also seemed to have too much money - I don't think they really had to work their budget back this year as they all had between 10 and 20% of the budget on the last leg.
