We informed the guests after we had booked and every one attending booked as and when they were ready, still 2 to book and get married in 4 weeks.
Just received email with prices if we need addtional upgrades ie flowers, photo's etc from WC, So will just email her all the guests names and what dates they will be arriving. The ones that booked through the same travel agent's as us are already linked to our wedding booking and we are all travelling on the same flights.
