I'm not sure if it's been mentioned here, but trays are no longer provided in the Lido.We also noticed that there are no trays in the Lido
Select your table - in the Lido, at the SeaView Pool or Lido Pool - and then go through the food line.
Signature and Vista class ships have a larger Lido than the smaller ships...but the same selection.
Sometimes at the late night buffet in the Lido (starting at 10 PM), HAL's signature pea soup is available. Also many other light (and not so light) bites....
So we hid a tray from room service in our closet, took it with us to the Lido and brought our food back to our room to eat on the veranda.
