Very random question. We have been on 2 cruises previously (not DCL) and had no trouble with sea sickness. However, I feel like I'm reading quite a bit on here about it, especially on 4 day sailings with people mentioning the ship moving faster on departure night and the last night to get home. So my question is, should we expect a different experience on our 4 night? Is it more susceptible to feeling the motion than say our precious 7 night?
