Sarah,
I took an AT&T hotspot from work out there last time I was there & it had a pretty good signal - much better than my T-mobile phone connection. Won't bring that hotspot this time though since I don't plan on dealing with work issues while there.
Not sure about Verizon.
They offer wifi - at what I consider a fairly high cost - $5/4 hours, $10/24 hours, $25/72 hours, $40/1 week. They indicate availability is limited & can be determined by locating & connecting to the network & then checking the coverage map. Not sure if the time for the wifi is by the clock - in other words from noon - 4PM or by the minute (4 hours worth of wifi time). Depending on this - it could be considered more reasonable.
