I'm new to Royal Caribbean and I have a question about shore excursions. The shore excursions were on sale last week, but I hadn't decided what to do yet. Now I've decided and they are more expensive. I've noticed that RC has sales all the time. My cruise leaves on 8/2/18. Should I wait for another sale? Or should I book them now so that I don't miss out on the things we want to do? Help please. Thanks!
