Where can I buy drinks cheaper than the hotel shop near beach resorts in the UAE?

Additional route detail: start from the Miramar hotel, walk along the beach past the next hotel through an abandoned area, then sneak onto the Royal hotel beach (tip: hide your hotel wristband so staff won't stop you), go up to the pool area and turn left to reach the shop. Just walking along the beach openly likely won't get you through — you need this trick.

Near the Royal M resort checkpoint (by the trash bins and what looks like garages), there's a small shop with a surprisingly wide selection of drinks.

Walking along the beach and turning right past two hotels, you'll reach an abandoned construction site; cutting through it and across the Royal M beach leads to a drinks shop with a wide selection and prices much lower than the hotel duty-free.

There's another small shop on the opposite side of the hotel grounds, near the main entrance/reception — not on the pool and beach side.
