Bags

Hi, I am packing bags for my trip starting next Friday and I am still in doubt of taking my huge back pack, or if this time I could carry a troller around. The thing is that I will carry some snorkelling and diving equipment and it´s a lot of weight. On the other hand I will be island hopping so, I am not sure a trolley will be a problem... What do you reckon?

Thanks!

Ialsnd hopping on the Flyer? Trolley is ok
