My parents are WDW veterans and we will be taking a family vacation during their anniversary. They always vacation around their anniversary however this year is different since my sister, my boyfriend, & I will be along. Any ideas on what my sister and I could surprise them with while we are there? In the past we have had a cake sent to them during dinner, made an ornament with a picture from vacation, and given them money for a hot air balloon ride and carriage ride. Thanks in advance!
