Hawaii had no tides, apparently, for obvious reasons.
The typical tidal range in the open ocean is about 1 metre (3 feet) (blue and green on the map on the right). Closer to the coast, this range is much greater. Coastal tidal ranges vary globally and can differ anywhere from near zero to over 16 m (52 ft).
A potential 2 foot increase in MSL would of course be problematic in some areas, but it wouldn't mean Manhattan would be 8 feet under water, unless you're making a movie, nor would it mean Orlando would become an ocean port city. It would be largely manageable in western countries, some areas that never should have been built in the first place would get abandoned.
