So, here's what I'd do. First, fire your travel agent. Second, limit your stay to Cabo San Lucas and environs. Third, if option two is not possible, buy a really good, heavy-duty tent. Tents available in the U.S. that I'd recommend include the Mountain Hardwear Trango 3.1 Arch ($625), Sierra Designs' Stretch Dome AST ($525), and the REI Geo Mountain 3 ($289). All are roomy, tough tents that can withstand wind- and snow-loading, and that don't have a ton of ventilation (forget the "year-round" bitnothing like that exists that can also take January in Canada). A good European-made tent available here is the Hilleberg Nallo 3 ($495), which is also substantially lighter than the three mentioned above.
Among tents available closer to you, MacPac's Hemisphere might be a good choice, although perhaps a tad small. It's about $1,000 in Aussie dollars, or about $550 American.
Have funBI guess!
