Carriers?

I feel like I'm spamming because I keep posting Lol.

I'm buying a travel carrier for the chins and I'm torn. I currently have two chins and I don't know if I want a double carrier or a single. It's unlikely that I would need to transport them both at the same time, however I feel that the double may be useful in that situation?

I'm looking at the quality cage carriers. It it worth an additional $40 for a double carrier?
