If it is a family holiday - north male atolls easiest - Honduranfush,Pasta Point or bit further away is Kandooma -- these places are covered by travel companies such as "perfect wave" "world safaris" "surf travel co" Their are a large fleet of boats coverind 3 diff areas North Middle and South Atolls also a couple of exotic travel companies let you partially tailor your trip. Might get some reccomendations on boats from breezers, I stayed at Lohis years ago and it was brilliant, but it has been upgraded and up priced and renamed Honduranfushi - it runs boats every day to Cokes RH and Chickens LH ( used to be same trip as these breaks are adjascent, Also to Sultans RH and Honkeys LH ( used to be same trip as breaks are adjascent) Also a trip to Jails RH June July and August usually gets the biggest swell cosistantly Steve
Are you going solo or with a family? I have been on a couple of boat trips (Carpe Diem and Carpe Vita) and plan to go on one with www.moontours.com.au in May. I personally like the boat trips as they can chase the swell and you get more variety. There are also opportunities for snorkeling and scuba diving - but that depends on the boat. I know a guy who went to Kandooma and enjoyed it. It has an exclusive right out the front, and there are other breaks nearby they will take you too (quarters, rip-tides, and others).
If you go north from Male you can get bigger waves but generally more crowded waves. If you go south, which I have done, you are supposed to get smaller waves but less crowds. As always, the size of the waves is out of your hands - I had one trip with pretty good size waves and another with smaller but still fun waves.
The time of year is the other deciding factor. The waves are bigger May-August (from memory) but the weather is less family friendly - more wind and storm sqalls - although some I have spoken to traveled in that period and had perfect weather. I went in April this year (2017) and had great weather.
