Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[Q]: I have a newborn in Cambodia and finally got to the point where I have a Lithuanian passport with Cambodian exit visa stamped in, valid for 7 days. I will need to leave the country with the baby and then come back and get him an E class visa upon entry, which then can be extended forever. I spoke about this yesterday at the immigration department and they seemed to be ok with the plan below. However from my personal experience I know that things at the border don't always run so smooth...

This one is tricky, as normally no one does visa runs in Cambodia since you can get indefinitely extendable E class visas. Still it is worth asking (and I have a slight Asian border-crossing phobia). I am planning to cross the Vietnamese border with the baby, while his mom will wait at the border to save on Vietnamese visa. Also, her Cambodian visa is 3 month single-entry. Then I get Vietnamese visas for me and the baby and then head ASAP back (baby is 3.5 months old and he has boob addiction. I have a bottle of formula, but he doesn't like it much. Also he hasn't been away from mom more than 10 feet ever). When doing visa runs is it wise to stay for some time in Vietnam, or can I cross immediately back and no one is going to blink an eye?

How long do I need to stay in Vietnam when doing a visa run from Cambodia for a baby to be on the safe side?

[Q]: I am a Spanish citizen, and next summer I will go on a cruise trip from Spain to France (only stopping in those countries). The organising company seems to be oriented to a USA public so they require the passport for the reservation/registration of the travel as well as the embarkation.

I asked them if I really needed the passport, given that my National ID lets me travel through all EU countries, and they replied that I do need to show my passport when I embark the ship.

Why do they require me to bring the passport?

UPDATE: after contacting the company a second time, they answered that the cruise line requires that I have my passport with me although this company is aware of my IDs grants

[Q]: My passport is swiss and I am living at Vancouver (with a student Visa valid until 2018) and I have a valid ESTA (until July 2016). Around July 15, I'll be crossing the border (between Vancouver and Seattle) to hitchhike in the USA along the west coast for about 2 weeks or 1 month.

At the moment I'll pass the border, I won't be able to indicate where I'll spend my first night. I won't be able to accurately say how much time I'll spend in the USA. Is it an issue?
