Explorer Alaska 2017 - 70s night or Rock Brittanica?

We are on the 6/2 sailing and would really love to know if they are doing the 70s disco night or the rock britannica one. Can somebody please let me know?

We have a group who all love the 70s night. Yep, we are the crazy bunch that loves to dress up and all :D so we were disappointed that last year it seems they did not do it.

Anybody just off the 7 day Alaska cruise on Explorer? Would love to hear from you :)

70's disco is on Day 3

and I believe rock britannia is on Day 6 (misplaced my compass for day 6)

If Graham Seymore is the CD, both will probably be put on. He is the wackiest CD in the RCI fleet, bar none. We'll miss him when he takes off and comes back only for fill-ins.

Graham was our CD for the may 19th sailing... Great character - and was always there at the ports and every major production on the sailing.
