Hi scottish_cpl from fellow Brits!
Ref booking and flights etc. The only two airlines that fly direct to Cancun are charters - Thomson (First Choice as was) and Thomas Cook. Thomas Cook have most frequent flights to Cancun and are currently the cheapest and their offerings (seat pitch etc) are broadly similar but TC are currently consolidating and cancelling flights to Cancun (our Aug/Sept flights have just been cancelled) so beware of that as this is likely to continue until tourist numbers go back up post swine flu scare. Thomson also have a weekly flight from Glasgow if that helps at all - they both go from LGW too (PS we find the Sofitel there better value for money and much nicer then the Hilton).
The other option is scheduled indirect flights which can be a better option if you pefer non standard lengths of stay (charter flights only on 7 or 14 days returns) or if you prefer to upgrade seats for the longer leg to the US. Choices there include US Airways and Virgin Atlantic etc and then a quick hop on Air Mexicana to Cancun. We are flying VA to Miami and then Mexicana to Cancun in Aug/Sept which allows us the 12 days stay we prefer as well as upgraded flights with VA so should arrive fairly refreshed plus chances of having a third flight now cancelled (also cancelled flights on us in May) is highly unlikely with a scheduled service.
As to who to book with/how to book.... we have tried various ways. The first time we booked a package with Peng Travel (
http://www.pengtravel.co.uk/) and they were very good and prices good - they packaged a deal up for us including First Choice Premium flights and included transfers. The next time we booked through DernnyP (
www.dennyp.com) as many people on here do and he was equally as good and we arranged our own air travel.
There are a few things to to bear in mind when deciding whether to use a US/UK tour operator or independent travel etc.... If you book through a UK TO then you are protected from currency fluctuations - can be a good or a bad thing - it would have worked out cheaper for us to have booked Desire direct or through Denny or another US TO on our first trip as the GBP ended up doing so well against the USD and then we lost out big time on our 2nd trip as booked through a US TO and paid in USD and then watched the GBP plunge before we made our final payment so that trip ended up costing us approx 2500GBP more than anticipated at the time of booking.
The other issue is UK travel insurance coverage for independent travel. We found that we were not covered for our Desire and other Mexico hotel booking on our travel insurance when our flights were cancelled in May because of the swine flu even through we hold two very well respected annual travel policies. Of course, had we booked a UK travel package then all our money would just have been refunded instantly as soon as the flights were cancelled but because the hotels were booked independently (through a US TO) we were unable to get refunds for one hotel but did mange to transfer our booking uintil May 2010 instead and for Desire we ended up transferring the money paid to our Sept trip that was already booked and then took a refund on the balance less a credit card penalty charge. We were happy with the outcome (although our cashflow wasn't as we then had to fork out for a completely new last minute holiday elsewhere) but the experience has made us think seriously about booking independently again rather than getting a UK TO to package up a deal if possible. Although we're already booked independently for Aug/Sept and May 2010 so will be a while before we have to cross that bridge again!
We understand that some people in the UK have also used Blue Bay Travel successfully.
Also agree completely with all the comments above about rooms. We also splurged on a week in a passion suite for our 2nd stay and we so wish that we'd just booked GV and saved the money to use instead for an extra weeks stay at Desire another time! You'll be glad of this once you get there as you'll soon realise that you'll be booking your return trip as soon as you get back home!
Hope you manage to make the arrangements you want and maybe see you in Aug/Sept?
