I think that's the correct designation for non-dependant
Major issue would be, besides the holiday (Christmas Day travel is usually good choice, particularly a Catholic nation) would be CARGO, so keep track of those warnings and luggage embargoes (carry-on ONLY sometimes for nonrevs)
I'd be very cautious about the return date and prepare to be flexible (I think you may have option to "buy your way out of the country" using Spirit one way?
if you get stuck.)
I went last summer and the airport must be all grown up by now.
