Eel grass and other seagrass is not a "problem." It is part of the amazing cycle of life, a component of the ecology of the Belize barrier reef and shore. Without the barrier reef, which slows the wave energy that over long periods creates wide sandy beaches, Belize would have the kind of beaches you find around many Caribbean islands -- nice for human swimming but with only a limited amount of sea life. With the barrier reef, a kind of rain forest under the sea, Belize has an amazing variety of sea life (not to mention a natural protection against storm surges).
As a practical matter, most hotels and resorts do remove sea grass from an area at the end of their pier or elsewhere to provide a grass-free area to swim. This is true north, south and in between. Hotels also regularly rake their beaches to eliminate grass that has washed up on shore.
