Hi L.,
I didn't read any books or do any particular method (or maybe I did do a method and just dont know what it's called since I didn't read any books!).
When my son was a baby/toddler, I kept to his normal schedule as closely as possible when we were travelling. We had a bedtime routine every night that I stuck to. He has never gotten a bath every night since it dries out his skin, but he gets one every other night. So, if it was bath night, I'd bathe him, then read him a story (I miss the short books... these chapter books now take so much longer!), sing him a lullaby, kiss him goodnight and put him in his crib (or toddler bed when he was old enough). Then I walked away. At home as long has he was fed and diapered, I let him cry (didn't really do that until he was around 6-8 months). When travelling though, I only let him cry for about 10 minutes before I'd soothe him, because being in a strange place is scary. He took naps at home in his playpen (or play yard or whatever they call them these days), so when we travelled it wasnt a big deal to sleep in it. If we went somewhere with a crib, I brought along his bumper, blankets, sheets, and crib toys so it would be almost like home. I never really worried about SIDS or anything because the monitor I had was one that measured movement and sounded an alarm if there wasnt any (Apnea runs in my family). If he stopped breathing the alarm would sound and jolt him awake (and me out of my skin). Since yuo are only a couple days into your chosen method, it won't be the end of the world if you can't stick with it while travelling. I like the other mom's idea about white noise - that might be a huge help with all of those people there!
