Can packages like Internet be bought for specific days?

[Cruisin Dovers]

Example: I only want Internet on two days of my 5-dat sailing. Can I just buy it for Day 2 and Day 4.

Same thing on beverage packages. Also on them does both guests have to buy a package? Can I buy a beverage package for just one day?

Welcome to the boards

For the internet, you could buy a 24 hour pass once onboard. The 24 hour pass costs significantly more than per day with a voyage duration cruise. For 2 days, it may be a negligible difference. 

Last I checked, it was $32.99 for surf and stream for 24 hours: https://www.royalcaribbeanblog.com/2019/10/31/royal-caribbean-wifi-guide-internet-sea

As for beverage package, no, you cannot get it for only some days. It's for the entire duration.

Only if one adult gets the unlimited alcohol package, then yes, the other adults in the same stateroom must buy it.

I kind of remember (or at least I think I do) they had a bucket of beer you could buy at a discount from buying them individually (like 5 or 6 bottles in the bucket). Not sure if they still have it. If you only plan on drinking on certain days (i.e. sea days) that might be an option to lower the cost
