I completed mine this morning and might I add it is an incredible attraction that I didn’t know my kingdom was missing.
This event has reminded me that as great as I think the enhancement attractions featured is, maybe the greatest addition the game has ever added (?), it’s even better than I remembered. I currently have 2 frozen attractions that I can’t send characters to, because they’re currently being enhanced! So glad that each enhancement level takes 4 hours to complete and times go up from there. Could you imagine how terrible it would have been if they were instantaneous?
