When lounging on the beach in the hot sun, it's easy to get desperately thirsty and drop $2 + on each bottle of water throughout your stay. To avoid this travesty (and I do mean travesty), I would recommend packing a few bottles for your trip and bringing one or two along with you each day. This helps avoid impulse beverage buys on the boardwalk ($3 lemonade, mostly ice) or buying a beverage with meals if you're ordering at the counter.
Another option is to fill up a reusable water bottle in the hotel or consider investing in a water bottle with a built-in purification system. Personally, I'm too much of a water snob to use the hotel water and just haven't bought the purified bottle, but what I did worked for me, and sure did save me a few dollars.
