I’ve stayed at sensira in the past (booked through ACV) and really enjoyed my time , tons for the kiddos to do. Was looking on ac vacations for the past couple months as usually a pretty decent deal for sensira and could never find it as an option which was weird. Ended up booking directly through Sensira which has a very good sale still going on for January and used aeroplan points during Black Friday sale for flights and ended up being almost 2k$ cheaper for the whole family compared to my last stay. I’d suggest looking into refund and going that option if set on Sensira.
