Hey Pam...Sorry I've not gotten back to you...been having some computer "issues"...it only lets me do what it wants me to do...lol...but I DO have an email in the works...will get it sent later today...hopefully! 
Yes, I was finally able to do the online checkin late last night. I could ONLY get to the online checkin site by logging in from the main page of the Holland America site. At the very top of that page, in the upper right hand corner, there is a login place...sign-in there instead of the login site further down the page (in the middle of page on the right) and it should sign you in and bring up a page where you can click on "On-Line Checkin" and begin the checkin process. Only took me about 15 minutes to complete everything once I got started.
I still haven't been able to access any excursions yet...says none are available at this time and to check back later...so, hopefully later today we should be able to access the excursions.
Well, the computer should be kicking me off soon, so I will work on that email to you and get it sent today! Talk with you soon!
