did you have a full year without periods before going onto conti option?
normally the insist on conti around the age of 53 or later.
if you start sequi hrt before this then you can move to conti after a year but that normal not offered when your younger like yourself.
could be your own periods are just still too strong for the conti option.
go back to evorel sequi before you go on holiday, no point being in completely new territory on a holiday as nice (and warm) as that.
stopping completely might have you with wider symptoms that might end up ruining your hols worse.
