Have you read the latest reviews added yesterday - both were very favourable. If it were me I would give it a try, I'm sure there's other hotels you've stayed in before that you thought were really good and yet others may have written really awful reviews about.
Last year Mum booked a cruise&stay holiday through Thomson only a week or two prior to departure, for all of the family. After the cruise we found ourselves in a hotel which was geared up mainly for elderly people and nothing for the 6 year old and two teenagers in our group to do. We enquired with the Thomsons rep about the possibility of being moved to somewhere with a bit more life/kids club etc. Another couple came right after us and talked to the rep about exactly the same issues - however they had read reviews prior to travelling and had suspected the hotel might not be suitable for their family and had written to Thomson stating their concerns before departure. The rep came back and told us that with it being July and very busy, there was really no availability in another hotel; the other family were however transferred. When I queried this with the rep, she advised that because the other family had made their concerns known to Thomson before departure, they had to make arrangements to move them and were given priority. I should add that they had to pay transfer costs to another resort so it wasn't free.
Perhaps it would be worthwhile therefore to write/email Thomsons and tell them that you have some particular concerns about the accommodation you are due to stay in, having read some recent negative reviews. Briefly outline your main concerns and ask that, if on arrival you find your concerns to be founded, Thomson will make necessary arrangements to move you to a suitable alternative accommodation. Take a copy of the letter with you for back up. Ofcourse you may have nothing to complain about, like so many others who have only good things to say about the hotel, but you have nothing to lose by writing.
Finally I would say please stop worrying as you will probably spoil your holiday before it begins, and may be looking for faults perhaps unneccessarily. Icmeler is a great place to visit, the people are very warm and welcoming there is so much more to it than just one hotel. Hopefully a few more good reviews will appear by the time you go
