Definitely worth buying a combi ticket. Haven't been to Sealife in NL for a long time. We were hesitant at first to go, but no regrets that we went. It's personal of course. If fishing doesn't interest you, then don't do this. London eye was an experience. Shame it was cloudy on our day. Also special because of the technology. Tickets are expensive, so one-time promotion. Time slot was for Sealife. Went to the ticket shop for the London eye. There an employee printed receipts with a time. Don't know if this was necessary, but do it just to be sure.

It was very quick and easy to get into both Sealife and the London Eye as we went very early. We started at Sealife when they opened at 10am and we’re queueing at the London Eye by 11:30am (it opens at 11am on weekdays). It may have also been quicker due to the heatwave but would still definitely recommend going as early as possible to anyone looking to avoid the queues.

We started from the aquarium and immediately after we did the spin on the wheel. The choice of time allowed us to arrive on time without too much advance and after the acceptance our visit to the Sea Life began. It takes about an hour and a half. At the exit we reached the London Eye and after being frightened by the long queue, in about 15 minutes we got into our cabin. They recommend arriving 30 minutes early and that's a great tip! On Wednesdays the wheel closes earlier than usual. Watch the timetables. There is no need to pay the skip-the-line supplement.
