Across the room or separate rooms is best in my opinion. At night mealy bugs turn into galloping horses and start crawling all over the place. I've caught them in this act checking on my orchids late at night ~2am. Seems like smaller and large over-grown bugs stay put, but the medium and juvenile ones begin crawling all over the place to discover 'new territories' and a separation of a couple of feet isn't much of a barrier to them. You'll also have to use different tools on the plants and make sure you don't touch the healthy ones after working with infected ones.
To deal with mealies I've used Bayer 3-in-1 Insect, Disease, and Mite Control spray solution. It works to instantly kill any bugs that come into contact with it and it also gets absorbed into the plant. It is also pretty cheap at a local gardening store (~$10 for a small spray bottle that lasts me at least a year). Also just physically removing any bugs that I see, wiping the leaves with a solution of rubbing alcohol, and flushing the plant with a stream of room temperature water + sterilizing the pot with hot water if I'm replanting it and notice an infection.
