Generally 30-35kn will be the limit for 90% of cruise ships. Minor deviations around this are related to direction, tug type and availability, ship configuration, masters experience etc. But you'd be unlikely to see a cruise ship operate above 35 knots.
Some of the issues with wind are around the 'swept path' (drift angle/crabbing) in a channel, also the ability to manoeuvre on and off the berth and also the ability to remain alongside (the mooring ropes & wire cables have limits and therefore thrusters may need to be left on all day to prevent them reaching their breaking strength)
