All the suggestions here are excellent. I guess, Good for You. is in order for you travelling alone, I guess.
Basically it will be eating 3 meals a day alone or eating with quickly made friends where you are at the time. Taking busses, cabs, out to dinner and much more alone or with actually strangers seems lets say different.
Do you prefer to just wing it alone or maybe would'nt it be more fun and enjoyable everything considered, to share all Aruba has to offer with someone you know well?
At a reserved table restaurant, Heather, dinner for one, sounds empty or am I wrong. Perhaps with a good friend or family member you might have a much better time????
