Seychelles hotel options for June next year (want to avoid seaweed)

We plan to spend 7-8 nights in Seychelles for our honeymoon in June and I'm getting a little overwhelmed with our options.

Currently considering: – Hilton Northolme – Hilton Labriz – Waldorf Astoria Platte Is. – Four Seasons Desroches Is. – Raffles Praslin

Has anyone stayed at above hotels recently to comment on how their experience was? One thing I really dislike about beach holiday is seaweeds getting swept up on the shore – if anyone's been in June I'd love to know which hotels were free from this issue!

Thank you in advance!!
