Ahoy, Melinda!
For the past two years, my husband and I have sailed with Disney Cruise Line during the "
Halloween on the High Seas" celebrations. We had wonderful experiences on each cruise.
Typically, the special celebration nights on any Disney Cruise are not held on the first or last nights of your sailing. If you log into your Disney Cruises Line reservation, you will be able to see which night that your Pirate Night will take place. This shows up as an "onboard activity". While I don't believe that Halloween Night will show up in this area, it is worth checking as well.
On your 7-Night sailing on the Disney Fantasy, you can expect three nights of
cruise casual attire (most likely your first and last nights plus one more). You will also have an optional formal night, where many of your fellow cruisers will dress to the nines in their very best ball gowns and tuxedos. This rings true on the optional semi-formal night as well. This leaves your last two nights as
Pirate Night and Halloween Night. As long as you have the correct attire packed, it truly doesn't matter which night happens when.
If you truly feel that you need to know which night is which, you can try calling Disney Cruise Line Reservations at 800-951-3532, and ask the very knowledgeable DCL representative. Be aware that this is subject to change. Last year, our Southern Caribbean cruise was diverted around some bad weather, so our nights happened in a different order.
I hope this helps with your vacation that is just a few days away!
Happy Cruising, Tracy V.
