I had a very good stay at the ITC Grand Goa.
They offer a free pick-up and drop using a bus that runs at fixed times. The resort is only about a 20 minute drive from the airport but once at the resort you feel like you are in the middle of nowhere.
I had booked the base Garden View room via HDFC Smartbuy. I have Marriott Gold Status. They upgraded me to a Lagoon View room at check-in. I asked for a Sea-View room and they gladly assigned me one. I'm guessing this was because it's off season and hotel was probably at less than 50% occupancy. Room had a beautiful view of the sea and beach. The room did get extremely slippery if you opened the windows though.
Kids loved the huge pools and the kids club. The kids club had 6 or so activities every day. Kids also got a band as part of the Marriott promotion (

The Beach was extremely clean and isolated. Hotel does have a couple of watchmen at the beach. A lifeguard is present as well.
Food was good. We ate the buffet breakfast in the restaurant and they had plenty of choices with several items changing every day. For our other meals we did ala-carte at the restaurants or room service.
A few very minor negatives -
Since it was monsoon hotel didn't have any deck chairs and/or towels at the beach. Even in the monsoon I think they should have a few of these at the beach. I even asked the concierge but they said it wasn't possible.
Staff were very friendly but somehow seemed to be missing that little extra that we've seen at other 5* hotels. For example at turn down most 5* hotels leave some sort of small chocolate or something. They didn't have anything at the ITC. When we bumped in to the house keeping manager we mentioned this and he said he would arrange it but we didn't get it.
The resort has golf carts to transport you within the resort. Even though it was off season the golf carts took a long time to arrive most times. I'm guessing it will be even more difficult to get one in peak season.
Overall I would love to stay here again.
