This may be a dumb question - if I book one or two excursions today, and add a few more in a few days, does Radisson keep track of ALL excursions?

In other words, will they delete the first ones I booked if I don't include them on the second request? The instructions on the online booking form are a little confusing... from the form:

>> If more than one form is submitted prior to your cruise, we will use the most recent submission and disregard any previous requests.

Thanks!
