I am replying publicly because at least some of the discussion is relevant to the board. WiMAX and 4G are in the infancy of their deployment, so I seriously doubt that either is available in your area. Verizon cell uses 3G, which, for internet, is poor at best.
If you have line-of-sight to the resort, and they have an unrestricted WiFi network, you can probably use an antenna to pick up service. However, you don't need an expensive Yagi. I built a simple 2.4GHz biquad antenna (the frequency used by WiFi) out of an old satellite dish and some simple parts. I use the antenna to receive a wireless signal from a security camera at my gate, ~1/2 mile from my house. Works great, and 100% reliable.
Here is an example. This guy was able to pick up a WiFi access point over 8 miles away:
