Checked in at 2:30am after a 16 hour delay from our flight in. Lost a full day of our vacation. We didn't let it disrupt us. Upon checking in, the front desk receptionist didn't crack a smile, didn't care about us being delayed. Just rushed to scan our travel things on our phones and charge us the upfront taxes and fees on our credit card. Subpar check-in experience.
Room was not great. Bathroom door didn't shut all the way. Stained carpet. Shower tile had mildew. No daily or even weekly housekeeping, but at least they were relatively quick to bring up towels when we needed them. That was really the only plus.
Initial concierge experience was okay. We did a bad job as far as planning activities prior to the trip so the meeting with the concierge helped. We booked a turtle snorkeling tour. We also booked a luau through a different company after being told by The Modern concierge that finding a luau this late was nearly impossible.
Of course, they make us do a timeshare sales presentation. This was a bad experience. The saleslady seemed nice and presentable, but she said a bunch of head scratching statements for someone that's in sales. We mentioned that our next trip was to Tennessee, and she gave a bewildered look asking who goes to Tennessee and what is there to do there? She also flat out said to us that we should not even be there (there as in, at the hotel). She stated that the fact that I booked the trip using my family's timeshare points meant that I shouldn't be there. This was a big turnoff to say the least, especially since we booked this trip on the phone with one of their own companys' reps and clearly stated the situation. I don't understand when these timeshare company's are going to learn that it's not 1997 anymore and high pitch sales tactics do not work.
Also, stubbed my toe really really bad on the way back to the hotel from a walk. It was bleeding. Get to the front desk. No first aid kit. She called someone, no luck. Just handed me a band-aid.
The hotel is on the less crowded side of Waikiki. Waikiki is crowded. Recommend renting a car and driving around the island.
The "restaurant" onsite is order at the counter, and is expensive. Pancakes were good though.
Was given a towel with a huge gaping hole in it at the pool. Pool can be okay if others around are just looking to relax for a couple hours. You can tell the people that likely use the pool as the highlight of their entire trip and there are plenty of those types at this pool.
The highlight of our trip was using our vouchers we received from our delayed flight and flying to Kauai on the second to last day. We had the best time there.

The hotel is mostly good. Pretty good location, close to the beach and easy walk to many things. Pool is small but an ok place to relax.

The hotel is pretty dirty. Carpets and bed sheets are stained and grubby. They are using COVID as an excuse to not clean rooms during your stay. Somewhat understandable, but when you’re there for a week they should clean the room at least once. Food at the Grove is small, expensive, not tasty or healthy.

Worst part is the concierge Shanghaiing me into some high pressure timeshare sales presentation. They will offer to book activities and say the hotel can get discounts. This is BS they will discount the cost by offering a “gift”, that they can withdraw at any time. They also take a $50 deposit when you pay for the activity. Which you lose when you don’t go to the 120 minute presentation, of which you must be available for 4 hours from the start time.

I can’t recommend staying here but if you do, don’t believe the concierge.

A Diamond timeshare owner, I was very pleased with this stay. Will be better when fully renovated, but still nice. If you do the luau, the food is good, the entertainment better by walking next door and seeing Hilton Village from the gate. Hoped the singer would sing the Hawaiian wedding song in English. Or really anymore songs in English. Loved a concert we happened upon at the HSO Waikiki Shell! Leonard’s bakery good but not worth an hour wait. Drove to the n shore to eat at Giovannis shrimp truck - another huge line. Drive to sea life park is as pretty - if not more so - than seeing the north shore, and much closer to Waikiki. Don Quixote great cheap souvenirs and Paradise Spa was awesome! Mai Tais at Royal Hawaiian Mai Tai bar spot on. Great trip!!
