Family suites with multiple bedrooms are like a glamorous apartment and they've become the mature way to travel. A bit pricey, but clearly we've learnt that you get what you pay for; a good standard of service is worth it, otherwise why go? Timeshares have built their success by ensuring there is consistency regardless of location; that, coupled with a high standard of service.

The interesting thing about timeshares is that many of the developments follow American standards when building and as a result may include features of the Americans with Disabilities Act (ADA). As a result one or two condominium units could be fully wheelchair accessible. Usually, this is not advertised. We won't venture as to why that might be. It would suffice to say that a token number of units is better than none.

The upside is that even if only a small number of official “handicap” units exist a level of accessibility naturally flows throughout the entire hotel/resort. This means that a wide range of people with milder disabilities, such as canes and walkers will be able to safely maneuver around environment.
Vacation developments are built around what the public want. In the future we might see a shift in concept. What is seen as a service act today could easily evolve into becoming a regular fixture. For example, placing a chair in the shower is considered a service but with enough request when hotels are next updated a built-in seat could be molded into the shower design.
Change will come about if enough people ask. If you don't need accessibility, enjoy, but do me a favor and ask anyway. Perhaps it may be there as a result when you do need it.

Happy trails!
