How about getting them a couple's dance lesson package with a professional ballet dancer? This will allow them to spend quality time together while learning something they both enjoy. Another idea is to get them a personalized ballet music box with their names and wedding date engraved on it as a special keepsake. Or you could get them a set of ballet-themed champagne flutes or wine glasses to celebrate their marriage.
Or you can get her/him a star map with the date of the wedding.
