We flew into Seattle the night before our cruise and stayed at Nexus. See my review on that, very convenient with their free shuttle to pier 66.
Infinity: It's a beautiful ship, elegantly decorated and it felt like a floating city. The glass surrounded elevators were great for the views when we were going up and down! The floor window in the Trellis offered a great view of the water below from 10 decks high! The grand foyer is a great backdrop for formal night photos. We enjoyed the indoor jacuzzi and thalossotherapy pool. We didn't get into the outdoor pool or Jacuzzi as it was cold for us on the Alaskan cruise. The view from Constellation cafe is beautiful with windows all around, perfect for the grand Alaskan vistas! We enjoyed watching the scenery with a drink in our hands when we left Juneau!
Trellis restaurant: Food improved significantly after day 1. Presentation of the food was excellent. Our waiters from Bali (Wayan and Nyoman) were amusing and friendly even though sometimes I got a soup or salad that I hadn't ordered. They really made us feel special. It's a beautiful restaurant especially with live music. Brunch one day was great with live music too! .
somewhat small but hidden storage in quite a few places!
