A Little Nervous

So, my boyfriend and I are extremely close and not talking to each other for more than a day is torture. My mom is planning a cruise in June that lasts 8 days. I won't be able to talk to him at all. I know you're probably thinking "who cares if you guys can't talk? It's a freaking cruise!!!!! Just go!" I know it really does sound crazy. Has anyone else gone through something similar and was everything ok? I'm scared not talking for 8 days will change things......
