We have just stayed at the Marriott with our granddaughter as part of a Legoland package. The room was large, modern and clean with all the facilities you would need. The staff were helpful and courteous and I would certainly recommend this hotel for Legoland or Heathrow stopovers. When we were there a large conference was taking place, obviously with an early start, which meant that breakfast was very quiet and leisurely. A good selection for breakfast and the staff were extremely attentive and helpful. The cafe bar is handy for people with kids to eat but the food is a little expensive. The fillet steak was rump steak at best but this was our only criticism.

I have stayed here extensively over the last 2 years. It fullfills my checklist of having a good gym, broadband connection and ironing equipment in the room.

The gym is really good providing extra value through yoga and spinning classes (which is included in the room price). However the service is un-even and so is the room-service not to mention the car park boom.

This hotel is good if you need to work (broadband) and it has one of the best hotel gym I have been too.

Very nice hotel. Big room. Nice restaurant (if slightly on the expensive side. Stayed here the night before catching an early morning flight from Heathrow. Very convenient for airport with shuttle buses operating. Also secure car parking while we were away

We stayed here for one night prior to flying from Heathrow. We were misled when we booked it, thinking it was the airport hotel - its not, its approx 15 minutes drive away - wasnt a problem though as the Hoppa shuttle bus travels to Heathrow every 30 minutes (20mins at peak times).
We had booked a double room which gave us two double beds for 2 adults & 2 kids. Room didn't have a great view (rooftops) but it was clean, spacious and well kitted out with tv, laptop connections, minibar, iron, tea & coffee facilities.
We decided to have room service - not bad - a good choice of menu and not extortionate rates (it actually looked cheaper than going down to the restaurant).
We left our car at the airport (special rates available for upto 15days). We were a little worried on arrival when the car park appeared full, however, there are 5 car parks in total which spread around the rear of the hotel.
It was excellent value at £99 for the room including parking.
