It very much depends on what you want from a holiday as to whether or not you enjoy San Miguel. The hotel rooms are very basic but if all you use the room for is to sleep, shower and change then they are adequate. The rooms are kept very clean and there are lovely views from the Hotel balconies (not so much at the Club depending on which room you get). The food is o.k. but not great - always plenty of choice but quite repetitive - twice a week they do either a fish or meat speciality night which are usually good.
The sun bed reservation at dawn is beyond a joke though - wish they would start locking the beds away until a reasonable time as we hate having to get up way before 7 a.m otherwise there are no sunbeds left (and it is the british who are mostly responsible)!! An alternative is to use the beach if you aren't participating in the daytime activities.
Included in the AI is use of canoes/boats and sailboards but you have to pay for pedaloes & banana boat.
The reason why so many people return, including us, is the animation team. They make everyone welcome and provide lots of activities throughout the day that you can join in if you want to - but will leave you to lie in the sun if that is all you want to do. They also provide most of the entertainment during the evening although there are some outside acts brought in. We have been for the last 6 years and are returning next year and even though we have seen the same entertainment each year, we still have a great laugh.
Not much else in the resort, but there are a few bars/restaurants and shops and some nice walks around the bay if it isn't too hot. The hotel is right on the beach - no roads to cross and very safe for children.
If you don't mind a relatively quiet resort then go for it - most people love it!! There are still loads of families who return year after year and they perhaps don't bother writing good reviews which would outweigh the poor ones. As far as I am concerned, the resort has not deteriorated in the time that I have been going there and the earlier reviews on this site are all very positive.
