We have booked alcoves many times , on different ships over the last several years . We always got a delicious cheese plate, water , towels , small lunch menu. As for the alcohol , we have never been offered bottle of vodka even though it showed that in booking . There were times alcoves did offered bottle of Veuve Clicquot .
our experience on last cruise Feb ‘23 on Silhouette we were offered cheese plate , a bottle of sparkling wine , bottled water ,towels , room service menu for lunch every day. The attendant will also get you drinks from the bar which are included if you have drink package.
I “believe “ water is provided but if you want a special kind / sparkling etc then that would apply to your drink package
Our recent sailing , we booked daily for 10 day cruise, I don’t think that made a difference on what was offered to us , it appeared all guests got water , cheese, wine, towels & lunch whether they just booked 1 day or multiple.
you could order a picnic lunch , prices vary . We never did, there were days we declined the cheese plate , sparkling wine & dined for lunch elsewhere .
there are many changes all the time so who knows 🤷🏼♀️
Hope this helps.
