I was on the May 26 - June 13 TA this year, in cabin PR703. That is a handicapped accessible cabin on Promenade, aft of the piazza, shops, etc on Deck 7 (quite convenient). Except for the aft suite I accidentally got on the Emerald in 2016, it's the best cabin I've ever had: large, w/a balcony to match & an excellent HA bathroom.
The balcony was the width of the old PR deck, including the wood flooring. The length was half again that of any balcony I've had ('cept the suite).
Fewer eating venues? Well, there was no Alfedo's or IC (I did miss both) but there was a Sabatini's, Bayou Steakhouse (I had a bigger, high quality filet like Crown Grill), 2 MDRs (both very good) & the buffet (fair to good; good desserts).
Yes, the wifi was lousy -- as it tends to be in the far northern areas on the globe -- but as long as I could get a message out to my DD each day, I didn't care. [DD worries about her Solo elderly mom.]
Everyone got a full refund of our wifi purchase.
The Island was my 10th (of 15 current) Princess ships. I've also been on 3 or 4 PCL ships no longer w/us. [35+ PCL cruises.] Except for the constant threat/discussion of Covid (I tested positive 3 days after getting home), it was a very pleasant cruise. I spent most of the 18 days on my large, covered balcony w/ my Kindle & coffee cup. I had delightful socialization at dinner w/all the Solo/Singles I met.
If the itinerary is something you really want, don't avoid the slightly older Island Princess.
