Alaska Southbound Pre-tour 1B Question

We are on the Pre-tour 1B sailing out of Seward on June 9th, 2017. For those of you who have done this tour can you tell me about what time we will arrive at the pier in Seward. We have early dining at 5:30 but I just booked the First Night Done Right with a dinner time of 6:00pm. Will I be onboard in time to make either one of these dining times. I thought about canceling or moving the Specialty Dining reservation but not sure what time to move it to. I called Royal but they didn't have a clue. Thanks.

since you have since taken this cruise, but no one answered, do you now have the answer? I'd love to know :D

Also -- if you have any tips from your land and sea trip? We've booked this for 2018. TIA!
