How about a personalized dance lessons package? You could get them a gift certificate for a specific number of private dance lessons or group classes with a dance instructor in their area. If they have a favorite type of dance, such as salsa or ballroom, you could find a local studio that specializes in that style.
Another option could be to get them dance-themed home decor, such as a canvas print of a couple dancing or a unique piece of wall art depicting dancers in motion.
You could also look into getting them tickets to a local dance performance or show, such as a ballet or contemporary dance piece. This would give them a fun night out to enjoy their passion for dance together.
Or you can get her/him a star map with the date of the wedding.
