I have been to the Golden Circle locations in March - at that time of year, the weather is extremely changeable. It would not be uncommon to encounter warm sunny periods, heavy rain, and snow showers during the same day. Much of the Golden Circle route is at low elevation, so driving will not prove to be a problem, even with a 2wd car. The only place where you have a good chance of encountering snow would be on the approach to Þingvellir National Park. Bottom line: can be done with a passengar car, easily done with a 4x4.

As long as you stay near the south or southeast coast, you will encounter early springtime weather - probably a bit rainy, but not too cold. If you go into the highlands or the glaciers, you will need a warm jacket, gloves, and a hat.

We stayed in the Radisson Saga, but I can't compare it to the Island, as we have never been there. I think that the Saga is a good value, with fairly large rooms and good views from the upper floors. It is not very modern, and is starting to show its age a bit, but was well-maintained and clean. Your 8-year old will like the buffet breakfast. Meals are so expensive in Iceland, we found it convenient and a saving to eat a big buffet breakfast, then skip lunch. The only downside to the Saga is that it is a bit of a walk (2km?) to downtown Reykjavik.

Thanks for that Alf..very helpful.. the nearest I will be going ice this time around will be Jokulsarlon !
