I have only been to to Aruba once, but have owned for several years and rent the off years. I bought at the Renaissance sight unseen because I fell into a dirt cheap week. We considered buying at the big Marriott's but upon visiting I have to say, for my purposes, I am glad we did not. The properties are beautiful and BIG and CROWDED and probably great if not traveling with small kids. I have 3 under the age of 4 and the smaller intimate low rise and location is easier for us to get around and close to restaurants ...just perfect for us. The beach on site, definitely not much to speak of, but again, it was calm and tranquil and great for my small fry. The private island is so much fun, the boat ride is fun, short and easy. My 18 month old, at the time just loved it... lots of pal trees to provide shade and she was able to take a nap on the beach. And the beach was great and not crowded, can't say enough. I thought we would sell our week, becuase I just own too many for the amount of travel one can manage with a 3 year olds and twin infants, but I jsut can't part with it. I would much rather go there. Now, if traveling with all adults, the Marriott's would be fine, I think.
If we need two bedrooms, I just use the next year's week, too. They are soo flexible and easy to work with and reservations are a breeze.
Oh, only after I type all this did I see you ahd a 24HR hold, so probably all irrelavent...Anywaym all that being said, I think you would have a great time either place, they each have their pros and cons. But if you prefer less crowed, I hope you took the Renaisance exchange.
