I personally would spend the extra 200 or so to fly to Coz so I wouldn't have to lug my luggage and dive gear on a bus, then a ferry, then a taxi all the way to my hotel not to mention the couple of hours of time to get to my hotel after flying from London. Much better to do Lon - Dal - Coz and return Can - Lon if the timing allows.
Also she will be in the International terminal and will only be changing planes and not staying... so no INS or Customs in the US. I would also check Lon - NYC or MIA or CHI or HOU etc.
Oh, maybe so. Looks like London-Cancun round-trip, non-stop starts at £638 GBP = $990 USD
Compared to London-Cozumel & Cancun-London, open-jaw, 1 stop each way starts at £827 = $1284
I couldn't get the site I wanted to work earlier so wasn't sure what the difference would be, so less $300 more to fly to Cozumel, returning from Cancun.
Bonus: the 1 plane change is in Canada so no having to mess with our TSA. I don't know what the Canadian agents are like.
Last time I flew out of Montreal, they had US TSA agents who live there to work our flight - who shut down the line for an hour to listen to a speech by George Bush. :silly:
You are right tho, in that it's nicer to land in Coz if possible - depending on the details of the trip, so your idea has merit. I would rather save $300 and go into Cancun, even with the expense & time on the bus & ferry, but then enjoy a private cab in Coz than the airport sardine van, but to each his/her own.
If she does pack light as she mentioned, she might also fly non-stop to Cancun, then take the commuter plane to Coz: 1 plane change in Cancun instead of Canada, and I am sure the commuter plane is much less than $300 one-way.
