Landing at Amsterdam, Schiphol Airport and then need to go to Ghent for start of tour. Is it relatively easy to get the Euro train from the airport to Ghent?
Yes, here is the site for the train:

The Netherlands and Belgian railways and privately owned Eurostar both operate trains.
If you want to book in advance, don't use trains operated by Eurostar (as they require a seat reservation and the ticket is only good for a specific train and time). A ticket on NS trains is good for any train on the day you pick and the seating is first come first serve in 1st or 2nd class.
There is a train station at fhe Airport. You can look up the available trains (VERY frequent) on the NS International website. If you are referring to the Eurostar trains, it looks like you can take one that has only a single connection, to an IC train in Antwerp.
Thank you so much for your help!
