Iceland Tour Review: Reykjavik, Hella, Thingvellir, Ice Cave, Glacier Walk, Golden Circle, Farm, 1-Week Trip

We would be sure to include the Jokulsarlon Glacier Lagoon.  We would plan earlier so we could get accommodation in Vik y Myrdal to have that as a second center for our holiday--omitting the time at the hotel near Selfoss because we did not think that hotel was up to its five-star rating.  The restaurant there was especially disappointing for dinner, though the breakfasts were good.  We planned to cook in the kitchen of our 4-bedroom apartment but found the kitchen woefully ill-equipped.  We did enjoy being near to Selfoss for restaurants and the grocery store.  
Plus the hotel was so close to the place we stayed in Hella that it seems better, more efficient spacing would be three nights in Hella and three in Vik y Myrdal.  Then, on the last night, because we returned to Reykjavik, we would have been better off staying at an airport hotel because our later return to the city meant effectively no time to explore and a very, very early airport departure for our 7:20 am flight.  
We thought the Blue Lagoon was overrated and would not prioritize it if we were planning the trip again.  
I think it's a good idea to give travelers more information about the changeability of weather and also to mention it might be a good idea to bring hiking poles--to err on the side of caution and encourage travelers to consider these issues more closely.  I did ask about clothing and the only guidance I got was to be prepared for the wind.
