Currently on the Royal now. Our cruise started with delayed boarding (was stated for 2pm but started at 1:30) due to noro on the cruise prior. But our cruise has been all smooth sailing, no notice of any illness going around, if anything since we have gotten on they have relaxed the alert level. There is also still another cruise between this one and yours. Could be deep cleaning under an abundance of caution but we didn't find out about our delay until the day before departure.
