This won't affect you if it's literally just a short vacation or even a business trip[1]. However, even if primary residence is only de-facto (generally, more than half a year spent at that location) you will probably be on the hook for tax. So beware of that 27-week holiday or business trip.
[1] exception: if you actually take payment in that location, e.g. selling stuff at a trade show, you need to register the business at the location you're visiting for that time as you are now operating from that country for VAT purposes. Ugh! VAT is a whole new can of worms anyway.
Ask an accountant. I suspect you'll be more or less free to choose your primary residence as long as you actually maintain an address there. But seriously, with any of these things it's best to talk to someone who knows the ins and outs of the tax laws of the countries you're visiting.

So what's the situation if you spend 3 months in 4 different countries each?
