The point of it is that it's feasible within modern technology - we have the propulsion and food production technologies on smaller scales and have proven they can be scaled, ultimately we're only really missing the orbital construction capacity to build something of that size.

Cryogenics, however, hasn't even been established as possible on humans. Only a few vertebrates have been frozen and revived, and only over short periods of storage with low success rates and drastically reduced life expectancy afterward. Even all our cryogenically stored corpses are just expensive caskets - reviews of the facilities have shown that even if it were possible, their technique causes more irreparable damage than standard embalming does, and isn't even done properly most of the time.

I saw on a Stephen Hawking documentary that if the ship reached 99% of light speed, the time dilation would be so that the crew would only experience a day for every year of travel. So 600 years = 600 days for the crew.
Like most of his stuff that wasn't written for the scientific journals, it's a bit simplified. At 99% of c, you'll experience one day for every seven days of travel. Doing a little playing with the calculator in my last post, you get to the 1 day=1 year point at roughly 99.999621% of light speed. (factor 363.21670029572545 - almost close enough to account for leap years even).
