Looking for a unicorn! July or October?

Getting married in July and looking to do a 2 week honeymoon starting mid July, there's a budget of 7k for flights and accommodation We want luxurious all inclusive with great food and cocktails included On the beach or pretty close to it. White or golden soft sands with clear or turquoise waters Direct flight from Birmingham or east Midlands airport, 8-10 hours flight time maximum High 20's plus temperature with as little chance of rain as possible Can't be too isolated, shops, restaurants, nightlife and opportunities for activities/excursions is essential (partner would lose his mind just relaxing on resort all week)

There is the possibility of delaying the honeymoon until end of October if this means it ticks more boxes but we want to honeymoonthis year (we're limited to school holidays of 2 weeks or longer) so either needs to be july or October

Please help as I'm lost and feel like I've travelled the world via Google and have only achieved frying my brain! 🙈
