Well the reason why code makes you change to a GFCI is because the GFCI detects current leaking and shuts the power down in a split second. That is quick enough to prevent anyone from getting shocked. Thats what they are pretty much worried about when they use GFCI's.

I would probably look into GFCI breakers instead of changing all the outlets, but you might have issues with your fridge.

A ground directs the power away from the situation and is supposed to trip the breaker.. In some cases having a ground is good because if you have a electronic device that has a power wire come loose and touch the casing it would trip the breaker. This would keep you from being shocked. On the other hand a lot of stuff now a days is double insulated and that would never happen.

To be honest with you not having grounded plugs isn't really that big of a deal. I have been living in homes without grounded plugs forever. I would say change the plugs in the kitchen and bathrooms to GFCI's for sure because you will be near water.

I would make sure that my main panel where ever it may be had a ground rod connected to it for sure.

Your electronic devices aren't going to blow up because they aren't grounded.

Nobody can guarantee that having a grounded plug will keep a surge from ruining anything either.

If you were interested in grounding plugs That could be a pretty big project. I'm not certain for sure, but I recall them changing the code to where you can't run a separate ground anymore. If thats the case its going to be an expensive job now.

To top it off in different areas they could add to the code because remember the code is "the bare minimum required" So I'm not sure what exactly the code is in your area.
