Our family of four would be paying several hundred dollars for a visit to Blue Lagoon. So, in the area that's south and east of the airport all the way over to Vik, does anyone have a favorite pool that has some type of a hot spring experience? I read about Reykjadalur but would really like a place that's more of a civic pool, I think Secret Lagoon will be too far out of the way. Maybe Grindavik http://www.visitgrindavik.is/site/grindavik-swimming-pool/en
or Laugaskarði , near Hveragerði
We will have a rental car and are in Iceland for 22 hours.
