We will also be at harbourside the first week in March with our grandkids, had our 4 yr old granddaughter with us last year, a few tips for you...
Sandra’s Taxi, very reasonable, friendly family business, google them and book ahead. Arrange airport pickup and return and ask them to take you to local supermarket to pick up groceries for your villa, keep in mind there is no oven. Ask Sandra to arrange a trip to local zoo, Great flamingo show for kids and kids get to feed parrots, my granddaughter loved the show.
Eat at Murray’s Deli, good variety of food for kids, chicken tenders, fries etc, ny style deli food at reasonable prices. Carmine’s, family style Italian Rest., large portions, if kids and family like Italian food, leftovers almost for sure lol kids menu at Margaritaville, a couple of blocks away from resort, you can walk to, other than breakfast, restaurant on harbor side is reasonably priced and has pizza, chicken tenders, fries etc for kids. There is a Marina Pizza shop as well, moderately priced as well as a Burger Shack, burgers, fries, shakes etc. for Carmine’s, reservations are a must, check what days these restaurants are open, they rotate openings and closings. There is a convenience store on prem, but pricey and limited items. There is a hotel shuttle that will take you shopping, for $7 a person???
Do no do a car rental, shuttle buses from hotel, run all day to all parts of Atlantis and ferry right next to harborside, for a small fee, takes you to downtown Nassau.
