If you want to rent by the week for chairs you can take anywhere, Craig at Packlight is definitely the way to go. Just google Packlight SXM. Great service, and a great guy. One caveat is that most of his chairs are 'sand chairs', i.,e,, low to the ground, so if you don't want that kind of chair, make that known when you make the reservation. We almost always rent an umbrella from him (no chairs) when we stay at Beachside Villas and I can state from personal experience that his umbrellas are pretty sturdy. Not as sturdy as the Club O umbrellas, but overall, a really good umbrella.
