We found a couple of afternoon options (eg
https://www.re.is/day-tours/gullfoss-geysir-thingvellir-afternoon-tour/ ). Clearly private tours can be adjusted. We have opted to hire a car as party of 5 and diy it.
Guys I was on an Iceland cruise in 2016 with
DCL and we have an active cruise meets thread for 2019.
We as a group have purchased a bus of 45 from Extreme Iceland, with a guide to do our times on a golden circle tour day 1 and blue Lagoon day 2.
It's cheaper than DCL, by a lot, it's more flexible, we have a Reykjavik drop off post tour. We know each other already on the coach, pick up at cruise terminal with Iceland experts, and they provided credit card links for everyone to pay.
As a set smaller group we can direct the day more.
I attach contact details.
Note do not think, Day and night, there is no night, - well no darkness, you can come back later. DCL will have a Cabanas Buffett 5 pm to 8 pm, and 10 pm to midnight. Also there is unlikely to be a show it will be a movie night, repeated later in the cinema.
Thinking " outside the box" will improve your options and save money.
( we have done the same in Akureyri).
