One thing to consider is that really quality zoom lenses will hold their focus throughout their zoom range, while those of lesser quality will likely have to be re-focused as you go. Not all bad with modern auto-focus cameras, but the need to re-focus as you zoom might slow down a budget camera. One of the main improvements on the more pricey cameras is the response time in the auto-focus drive.

One thing more- while you shouldn't scrimp on lens quality, be sure to invest in at least a good UV filter, if for no other reason than to protect the investment of your new lens. A filter replacement is way cheaper than a scratch on your lens optics. And If it were me heading to Barbados, I'd invest in a circular Polarizing filter. The clouds down there can provide some pretty dramatic imaging with a polarizer.
Hey thanks man you have been very helpful...I think im gonna go with the Canon EF 70-300mm f/4-5.6 IS USM for now. I'm hoping that it will get me the extra zoom i need. Apposed to my 28mm-135mm IS USM. Also, I do plan on getting a circular polarizing filter for both of my lenses. Hopefully, I come back with some great pics that I can share with you all.
