Yes, you are paying the first $200 of your trip's total price.
And by the way, just in case this matters to you ....
If you are booking by phone, they will say or allude that you need to make the deposit immediately by credit card ... NOT TRUE. You have 14 days to make the deposit, which you can do by mailing a check or by calling back within that 14-day window. Of course, if you miss that window ... POOF ... your reservation disappears like the honey in Pooh's honey pot.
