I like your thinking. I just don't think it's worth it, at least for our last night to be at a high-end hotel. We'll be coming back from the island and we have an early morning flight at 8am. I am still considering the Sofitel for the first two nights.
I just checked the Sofitel on the first two nights we arrived and it's showing $1,300 in the app. That's not terrible considering we paid $500 a night earlier this year for the Sofitel Noosa and got a cough room with a view of a car park.
Looks like we land from BNE about 5pm so could potentially make it the executive club for drinks and canapes and settle in for the next day, use the adults-only amenities and then leave to have three nights on an island.
I love the look of Tokoriki but I've never paid that much for a hotel in my life. I agree it doesn't seem a good value to do the all-inclusive meals. We just wouldn't eat that much, particularly when there's a buffet breakfast included.
By the way, are you familiar with the app
Ratedrop.net? I've been using it for the last year. It's only about $7 a month and it saved me hundreds of dollars with Accor booking. You just put in your Accor booking and it notifies you as soon as the rate drops so you can rebook.
It's been a great investment. I think I'll book the Sofitel and see if the rate drops.
EDIT: I just remembered I get the 4th night free via Luxury Escapes with my Citi Prestige card, so we could have 4 night on Tokoriki for the price of 3....
