We bought all of our alcohol at Target, both wine and hard stuff. We also stopped at Safeway...their wines may have been just a bit cheaper, but not worth going there just for that. We did not think they were much higher priced than at home overall. The ABC store across the street is higher, but not crazy high. Any place beats the cost of one drink at the resort.
It is not fun packing alcohol. When we did a
Disney Cruise two years ago, we packed alcohol into our checked bags for the flight to Florida, then had to unpack them to put into our carryons for boarding the ship. I worried about breakage....especially the way the bags are handled!
We also picked up steaks and burgers at Target and used the wonderful gas grills at the resort. There is also a fresh produce market in the same parking lot. They have some great stuff....you can also get salads and sandwiches made there. Their spice section is wonderful....we brought home some black hawaiin sea salt and some other interesting things.
Have a wonderful trip. We went around the same time last January. If you carefully walk two lagoons up (behind Paradise Cove) you may see some of the smaller type sea turtles basking on the rocks.
We had great weather and also got to see some monster waves at North Shore.
Avoid morning and evening rush hour at all costs.
