I like the suggestions mentioned in the 2 previous responses to your post. I think some level of implementation would be practical.
My family of 6 or 11 (depending on the year) mostly spend our time on the beach. We do use the pool, but do not use the lounges except as a place to put our towels and other items (usually only 1 or 2). We swim or leave, and do not lounge around the pool. Over the years, people have arrived at Casa Ybel from who knows where, parked in our lot (mostly near the tennis courts), unloaded their car(s), walked through our property, and set up camp on the beach, including coolers, which is a major giveaway. The beach, of course, is public property. During a slow period, there are few legitimate Casa Ybellers and few interlopers, and, except for the principle of the situation, tolerable. However, during a high volume week, such as week 52 and, I suspect, Easter and a very few other weeks, the beach has more legitimate and interloper density, and it gets crowded.
One of the selling points of Casa Ybel for us was the low ratio of condo units to beach frontage, likely the lowest on the island. This also makes it appealing to outsiders. I understand the beach is public, and I cannot just carve out my space and expect others to remain 100 yards away. But, even during a high volume week, if just legitimate guests use the beach, it is possible to set up a single line with each party having full, unimpeded view of the gulf and 40’ or more spacing. When you add even 5 or 6 more groups (not uncommon in front of buildings HIJK), then there are issues. Often, these folks don’t respect your space and plop down right in front of you. Sometimes there is annoying and loud music. Further, we see them using the pool.
As I’ve said many times, there are a number of ways to combat this problem. The existence of the Thistle Lodge certainly makes things dicier. But even saber rattling signage will have an effect. Some, maybe even many, people are intimidated by signs that declare cars will be towed if they don’t have a guest pass. A roving security guard also is effective. Totally eradicating the problem is probably impossible, and certainly not cost effective, but much can be done, I believe, within our budget (whatever that is).
There is another consideration here, I believe. Having used essentially the same MO since we first started coming to Casa Ybel, I can say with confidence that the interloper situation is far worse than 10+ years ago, and I do not recall any problems in our early years. No, I don’t have data. It is my contention that the word is out that Casa Ybel is not only a great place with a beautiful beach, but also a soft touch. It takes years for this reputation to be earned, and it will take years to change it.
As previous posts have mentioned, YES, the problem is worse than ten years ago! I have personally witnessed all the examples of interloping and you know what? The word is out. Casa is an easy get when it comes to trespassing = no consequences.
On our second week now and don't see what all the fuss is about. We have spent every day by the pool except for the recent rainy days. There have been kids who had to be told not to rough house in the pool and people have been asked to keep their drinks outside of the pool but I imagine that occurs at every pool. McT's restaurant is gone and there is a new breakfast restaurant called Bennett's Fresh Roast opening soon near the where the Lazy Flamingo is. The Sundial opened 3 new restaurants too and Doc Fords opened a second location at the entrance of South Seas. We eat out a lot on vacation.
